    Division.
    No. 00 C 7265--William J. Hibbler, Judge.

    Before Bauer, Coffey, and Manion, Circuit
    Judges.
    Bauer, Circuit Judge. United Airlines
    ("United") appeals from the denial of a
    preliminary injunction which it had
    sought against the International
    Association of Machinist and Aerospace
    Workers, AFL-CIO ("IAM") in order to com
    pel IAM to exert every reasonable effort
    to discourage its member mechanics from
    engaging in a concerted work slowdown at
    United. For the reasons set forth below,
    we reverse the decision of the district
    court.
    BACKGROUND
    United is a "carrier" as defined by sec.
    201 of the Railway Labor Act ("RLA"), 45
    U.S.C. sec. 181. IAM is the certified
    exclusive bargaining representative of
    six different crafts or classes of United
    employees, including the mechanics craft
    or class. In 1994, IAM and United
    negotiated a collective bargaining
    agreement ("CBA"), which by its terms
    became amendable on July 12, 2000 The
    parties entered into negotiations in
    December of 1999 but were unable to reach
    an agreement by July 12, 2000.
    In September of 2000, United and IAM
    jointly applied to the National Mediation
    Board ("NMB") for mediation pursuant to
    sec. 5 of the RLA, 45 U.S.C. sec. 155.
    The RLA requires both parties to maintain
    the status quo during mediation (that is,
    it forbids either party from unilaterally
    altering the working conditions in place,
    broadly defined). Negotiations between
    the parties broke off on October 31, and
    resumed on December 7. The talks continue
    as of the time of this decision.
    Beginning shortly after July of 2000,
    and continuing in varying degrees up to
    the present time, United has experienced
    various maintenance-related anomalies
    which it interprets as a deliberate "slow
    down" campaign on the part of its
    mechanics. Specifically, United has
    experienced a greater than normal number
    of maintenance write-ups/1 by mechanics,
    longer than usual "cycle times"/2 at
    its Indianapolis Maintenance Center, a
    sharp increase in the number of aircraft
    held out of service for unscheduled
    maintenance,/3 and an increase in
    maintenance-related flight delays and
    cancellations. By November 10, 2000
    United suspected that IAM was directing
    or encouraging the work slowdown, and on
    November 10, 2000 United Senior Vice
    President Andrew Studdert wrote a letter
    to IAM District Lodge 141-M General
    Chairman Scotty Ford calling on the union
    to halt what he called the "concerted job
    action by employees represented by
    District Lodge 141-M." In the letter,
    Studdert complained that IAM employees
    were submitting excessive mechanical
    write-ups making erroneous claims of
    missing equipment, and failing to work
    scheduled overtime. Studdert
    characterized the mechanics’ conduct as
    "clearly concerted and appear[ing] to be
    in direct response to misleading
    communications from the IAM about the
    Company’s position at the bargaining
    table, inaccurate descriptions of other
    management decisions, and clear ’work to
    rule’ campaign directives from District
    Lodge 141-M." Studdert then reminded Ford
    of IAM’s duties under the RLA to maintain
    the status quo during ongoing
    negotiations, and noted that IAM’s
    failure to observe this duty was illegal
    and enjoinable in federal court. Finally,
    Studdert requested IAM and its members to
    return to the status quo immediately. He
    demanded an immediate end to IAM
    communications containing misleading
    information about United’s bargaining
    positions, as well as "an immediate end
    to work to rule directives, and any other
    steps necessary to secure an immediate
    end to this disruptive behavior."
    On November 14, 2000, Scotty Ford sent
    Studdert a letter in response. In the
    letter, Ford stated that he "greatly
    resent[ed] what can only be seen as an
    attempt to threaten and intimidate this
    Union and its members during these
    negotiations." Ford denied that IAM had
    encouraged any employee to violate either
    the CBA or the RLA, and he requested
    Studdert to present specific evidence
    that either the District or any of its
    officers were doing so. Ford asserted
    that recent communications from the IAM
    District 141-M Negotiating Committee had
    "repeatedly advised the [union]
    membership not to take part in any job
    action and has gone so far as to
    recommend that members work overtime."
    Ford contended that recent actions by
    United management (including the
    "discharge of 108 mechanics in Los
    Angeles") were the "true reason behind
    any so-called ’disruptive behavior’" on
    the part of IAM mechanics, and he accused
    United of trying to "censor" IAM
    communications.
    One week later, United moved for a
    temporary restraining order ("TRO") and a
    preliminary injunction. United asked the
    court to prohibit United’s mechanics from
    engaging in a slowdown campaign and to
    order the IAM, its district and local
    lodges, and their officers to take
    specific steps to stop ongoing slowdown
    activity. In support of its motion,
    United produced three categories of
    evidence: (1) statistical evidence of a
    slowdown campaign, along with testimony
    by United managers describing their
    personal observation of slowdown
    activities by mechanics; (2) letters and
    bulletins issued by IAM District Lodge
    141-M and IAM’s local lodges during
    October and November 2000 which United
    claimed constituted a deliberate slowdown
    campaign directed by IAM; and (3) letters
    and flyers posted by individual mechanics
    during the same period that encouraged
    work slowdowns and other job actions.
    These categories of evidence are
    addressed in turn.
    (1) Statistical evidence of a
    slowdown/managerial testimony
    United’s statistical evidence revealed
    the following: (1) a jump in the number
    of maintenance write-ups from historical
    levels of 1050-1100 maintenance items per
    day to 1350 per day in July of 2000, and
    climbing to almost 1500 per day during
    the first two weeks of November (after
    the contract talks broke off); (2) an
    increase in cycle times for scheduled
    maintenance checks at United’s
    Indianapolis Maintenance Center beginning
    in July and rising to almost double their
    historical averages during September
    through November 2000; (3) an increase in
    the number of aircraft held out of
    service for unscheduled maintenance at
    any given point from the historical
    average of roughly 12 to nearly 30 in
    July, followed by a slight decrease in
    September through November, and a
    subsequent increase to 35 a day during
    the first two weeks of November; (4) an
    increase in the percentage of United
    flights that are delayed due to
    mechanical problems from the historical
    average of roughly four percent to over
    seven percent in July through August
    2000, then dipping to six percent in
    September and October, and climbing again
    to approximately eight percent during the
    first two weeks of November; (3) A
    doubling of the percentage of flight’s
    cancelled due to mechanical problems from
    the historical average of roughly one
    percent to over 2.5 percent in July
    through August 2000, followed by a
    decline to approximately 1.5 percent in
    September and October, and another
    increase to two percent during the first
    two weeks of November./4
    In addition, United produced testimony
    from the managers at each of United’s
    large and medium-sized maintenance bases,
    many of whom described their personal ob
    servations of mechanics making repeated
    and unnecessary references to maintenance
    manuals, refusing en masse to work
    voluntary overtime, writing up
    maintenance items immediately before
    flight time (causing delays and
    cancellations), and writing up cosmetic
    defects which ordinarily would be
    ignored, such as torn foot rests, worn
    arm rests, and chipped paint.
    (2) Letters and bulletins issued by IAM
    District Lodge 141-M and other local
    lodges
    On October 3, 2000, District Lodge 141-
    M--the body authorized by IAM to
    negotiate the CBA between the mechanics
    and United--sent a bulletin to all IAM
    aircraft maintenance personnel stressing
    the importance of ensuring that aircraft
    be in airworthy condition before being
    returned to service as required by the
    federal aviation regulations. The
    bulletin noted "apparent inconsistencies
    in the procedures of reporting
    maintenance discrepancies on United
    Airlines aircraft." Specifically, it
    noted that according to IMCOP operating
    procedures, mechanics should report
    discrepancies to the Airframe team leader
    or the lead mechanic "to determine
    whether a write-up is necessary," but the
    Administrative and Operating Policy
    suggested that write-ups can be generated
    by dock personnel. The bulletin urges
    individual technicians to write up
    problems and to repair, replace, or defer
    the discrepancy if necessary, and it
    further exhorts the mechanics: "If you
    find something wrong on an aircraft,
    ACTION MUST BE TAKEN!" (emphasis in
    original). First Norman Aff. para. 8,
    Exhibit 1.
    On October 13, District Lodge 141-M sent
    a bulletin to its member mechanics under
    the prominent title "Negotiations." The
    bulletin opens by describing the recent
    progress of the negotiations between
    United and the IAM (which it casts in a
    negative light), and proceeds to admonish
    member mechanics to "work safe":
    This week we can report that almost no
    progress was accomplished . . . Your
    Committee has made it clear that any
    company proposal involving job
    concessions not withdrawn would place
    these negotiations in jeopardy and could
    result in the IAM seeking self-help. . .
    . We have been made aware of several
    incidents of aircraft damage around the
    system. Luckily, no employees have been
    injured. We hope that the stress and
    anxiety of these contract negotiations
    have not been contributing factors. We
    need to remind every employee that SAFETY
    COMES FIRST! We don’t need aircraft
    damage and certainly do not want anybody
    injured. PLEASE WORK SAFE, take no part
    in any job action, don’t believe rumors,
    and remain solid behind your Committee.
    United introduced testimony from some of
    its maintenance officials that phrases
    such as "work safe" are commonly
    recognized by United mechanics as code
    words calling for a work slowdown.
    A posting on the IAM website during the
    same time period echoed this message to
    "work safe." An October 27 website
    posting by the District 141-M negotiating
    team recounts the recent status of
    negotiations, and then reminds members to
    "not believe rumors," "be supportive,"
    "[w]ork safe," and "[t]ake no part in any
    job action." Id. at para. 10, Exhibit 3.
    In addition, a November 10 posting on the
    same website reported that the NMB had
    adjourned the current round of
    negotiations, and stated that United had
    not submitted realistic wage proposals.
    It announced that IAM had called for a
    release from further negotiations "in
    order to begin the 30-day countdown," and
    quoted Ford as saying: "We do not believe
    United will bargain seriously without
    additional pressure . . . . After 6 years
    of dedication and sacrifice by IAM
    members and 6 years of historic profits
    by United, it’s payback time . . . . The
    sooner United understands that the
    better." The posting concluded: "while
    the Railway Labor Act allows for near-
    endless negotiations in the airline
    industry, the membership of this union
    does not." Id. at para. 11, Exhibit 4.
    On October 19, 2000, one of IAM’s local
    lodges issued a bulletin which stated:
    "The company started its ’job action
    letter campaign’ Tuesday in retaliation
    to the I.A.M. Negotiating Committee’s
    update of October 13, stating WORK SAFE!
    This has obviously made the company
    upset." The bulletin went on to excoriate
    United for its strong-armed management
    techniques, and asserted: "The ugly truth
    is we are at war, all out war!" Id. at
    para. 13, Exhibit 6.
    United also presented bulletins and
    memos which it claimed were issued by
    other IAM Local Lodges/5 that stressed
    the "safety first" message even more
    emphatically. For example, a bulletin
    which purported to come from IAM Local
    Lodge 1781 prominently displayed the
    words "Safety First" twice and stated:
    We must work even harder at performing
    our jobs in a safe manner . . . . We must
    also be aware that we have a
    responsibility to comply with the many
    FAA and CAL/OSHA regulations required to
    perform our daily jobs, no matter how
    long it takes . . . . It is imperative
    that, in these times of stress,
    uncertainty and distractions; working
    safely, within our skills, must be our
    number one concern. NO JOB IS SO URGENT
    THAT IT CAN’T BE DONE SAFELY. (emphasis
    in original). Id. at para. 14, Exhibit 7.
    In late October or early November, three
    virtually identical bulletins appeared in
    three separate United maintenance bases
    under the headings "Negotiations 2000,"
    "Millennium Negotiations," and "Lodge
    1781 Strike Committee." One of them
    appeared on an official IAM bulletin
    board inside of a locked, glass case. The
    bulletins read, in part:
    In keeping with the "Safety First"
    ideal, it is time for us to examine our
    tools and equipment. Greasy wrenched
    could result in personal injuries and
    damaged parts. Check your boxes and
    tools. If they haven’t been cleaned
    lately, give some thought to safety and
    clean them daily.
    Some tools need lubrication to work
    properly. Knives need to be sharpened to
    work efficiently and safely. Now is the
    time to take care of these needs.
    Machinery and equipment also should be
    checked for safety. Fork lifts, tugs,
    drive belts, fitting devices, baggage
    equipment, food service equipment . . .
    all should be checked thoroughly. If it
    isn’t safe, shut it down and get it
    fixed. (emphasis in original).
    Finally, a memo bearing the IAM seal and
    purporting to be from Local Lodge 1487 in
    Chicago further reinforced the message
    under the heading of Work Safe. The memo
    complains of excessive and inappropriate
    discipline by United which it
    characterizes as constituting "an
    environment of intimidation." The memo
    goes on to say, in part:
    We, as the Grievance Committee, feel
    obligated to advise you how to stay out
    of trouble during these oppressive times.
    We advise you to take the advice given by
    Scotty Ford, D-141M President and General
    Chair, on the bulletin dated Oct. 15,
    2000 and WORK SAFE. Do not let outside
    influences distract you from the job at
    hand. The utmost importance must be put
    on SAFETY so we can return to our
    families after work.
    They created this atmosphere, now we have
    to deal with it. If you do not follow the
    rules and procedures you will be
    disciplined up to and including
    discharge. For this reason we are asking
    our members to be careful, follow all
    procedures and WORK SAFE!!! (emphasis in
    original.) Id. at sec. 16, Exhibit 9.
    IAM denies that it issued these
    bulletins.
    (3) Letters and flyers posted by
    individual mechanics
    United also produced a number of
    leaflets, flyers, and website messages
    which it claimed were distributed in
    United’s maintenance facilities or
    directed at United mechanics that
    explicitly acknowledged and encouraged
    slowdown activities. For example, a flyer
    entitled "TURN UP THE HEAT" and addressed
    to United’s CEO, Jim Goodwin, which was
    posted in San Francisco stated: "We, as
    professionals, do not enjoy work
    slowdowns, but you leave us no choice. .
    . . NO OVERTIME November 21-28[:] 1.
    Starting 0500 11/21[;] 2. No Four
    Overs[;] 3. No Easy-Hours[;] 4. No Early
    Starts[;] 5. No Working Through Lunch.
    P.S. We will remember those who work!!"
    Id. at para. 20, Exhibit 13. In addition,
    United claims that it received other
    flyers on or about November 7, 2000,
    which stated, respectively: "[L]et’s
    screw the bastards royally. It’s time to
    turn up the heat," and "LET’S MAKE THIS
    THE HOLIDAY SEASON FROM HELL!!!!!!!!"
    Id. at para.para. 21 and 22, Exhibits 14
    and 15. The third flyer which was signed
    "IAM AFL/CIO" but was not on IAM
    letterhead stated: "the members of the
    International Association of Machinists
    at United Airlines wish to make it known
    that they must act aggressively against
    their company during the upcoming holiday
    travel season. Actions to be taken will
    include massive slow downs and delaying
    tactics beginning in late November, 2000
    . . . ." Id. at sec.23, Exhibit 16. IAM
    denies issuing any of these flyers.
    On November 17, 2000, after hearing
    argument from both sides, the district
    court found that United was "likely to
    succeed on the merits of its claims that
    Defendants are violating the RLA," that
    United was suffering "immediate,
    substantial, and irreparable injury" in
    the form of lost revenue and consumer
    goodwill, and that the harm to IAM from
    the issuance of the TRO would be
    "inconsequential when compared to the
    loss and hardship which United and the
    public will suffer." Accordingly, the
    court issued a TRO prohibiting IAM and
    its members from engaging in or
    encouraging any kind of slowdown activity
    or other work action designed to
    interfere with United’s airline
    operations, and ordering all officers of
    IAM’s district and local lodges to "take
    all reasonable steps within their power"
    to prevent the enjoined actions, by
    (inter alia) notifying all IAM mechanics
    of the issuance, contents, and meaning of
    TRO in "the most expeditious means
    possible," putting this notice on IAM’s
    websites and recorded telephone hotlines,
    instructing all IAM-represented personnel
    to resume their normal working schedules
    and practices, and directing members to
    end any slowdown activity (and any
    communications encouraging such activity)
    upon pain of fine, suspension, or other
    sanction by IAM. In response to concerns
    expressed by IAM’s counsel that the TRO
    might discourage IAM mechanics from
    performing their jobs with their usual
    care, the court added to the TRO the
    following sentence: "This notice in no
    way is meant to have impact upon each
    mechanic’s exercise of their usual
    diligence in providing appropriate safety
    for all aircraft."
    The TRO was not initially effective.
    Indeed, the situation appeared to worsen
    considerably after its issuance. In the
    days following the TRO: (1) the number of
    write-ups increased to an average of over
    1500 per day, with an all-time peak of
    2037 on November 22; (2) from November
    18-30, the average number of out-of-
    service aircraft increased to 42 with an
    all-time high of 52 on November 26; (3)
    during the same period, the number of
    maintenance-related flight delays
    increased to 8.8 percent of all flights;
    (4) in the same period, the number of
    flight cancellations due to mechanical
    problems increased to 2.5 percent of all
    flights. Each of these figures
    represented an appreciable increase from
    the corresponding levels for the month
    before the TRO was issued (which were
    already substantially higher than
    historical averages). The parties have
    differing explanations for this. United
    believes that IAM failed to comply with
    the TRO./6 IAM claims that it fully
    complied with the TRO, and argues that
    the ineffectiveness of the TRO
    demonstrates that, to the extent that any
    illegal work action was occurring at all
    (which IAM did not concede), such action
    was being performed by dissident
    mechanics who were not in the union’s
    control.
    On November 21, IAM filed the
    declarations of seven of its officers
    describing its compliance with the TRO.
    On the following day, United filed a
    motion seeking to hold IAM in contempt of
    the TRO. On November 27, the parties held
    a telephonic conference with the district
    court, during which the court instructed
    United to identify particular individuals
    who United felt were continuing to act
    inappropriately, and to inform IAM of
    who, when, and where such inappropriate
    actions were taking place in order to
    facilitate IAM’s efforts to implement the
    TRO. The court also admonished IAM to "do
    all in its power . . . to effectuate the
    stoppage of any work action by the
    mechanics," and to "take appropriate
    aggressive actions in those instances
    where the company has pointed out
    continued work actions are taking place."
    Shortly thereafter, United supplied IAM
    with the names of 144 mechanics whom it
    believed were performing an excessive
    number of write-ups and identified
    stations that were suffering a
    disproportionate number of problems.
    United asked IAM to counsel the mechanics
    that it had identified. It also requested
    the IAM officers who are individual
    defendants in the case to conduct
    personal briefings at each work location
    to "explain what the TRO and status quo
    means," "explicitly explain that all
    slowdown messages are no longer valid,"
    and to "convey with absolute sincerity
    and commitment that they IAM will abide
    with the TRO." United also asked IAM to
    remove all materials encouraging the
    slowdown (including the original IAM
    bulletin announcing the TRO), and to post
    the TRO along with two letters from Ford
    on all bulletin boards. In addition, on
    November 30, United’s counsel told IAM’s
    counsel that United had incurred $66
    million in damages due to the mechanic
    slowdown since the issuance of the TRO.
    Immediately thereafter, the situation
    began to improve. Between December 1 and
    10: (1) the number of write-ups dropped
    to an average of 1,306 per day; (2) the
    number of out-of-service aircraft
    decreased to less than 30 per day; (3)
    the percentage of flights delayed for
    mechanical reasons dropped to 6.5
    percent; and (4) the percentage of
    maintenance-related flight cancellations
    dropped to an average of 2.2 percent.
    These numbers reflected measurable
    improvement from the levels in place from
    November 18-30, although they remained
    significantly higher than historical
    levels in all categories. Once again, the
    parties provide conflicting explanations
    for this turn of events. United argues
    that the improvement was caused by IAM’s
    belated efforts to abide by the TRO by
    aggressively discouraging its members
    from engaging in a work slowdown. IAM
    counters that the amelioration was due
    mainly to United’s long overdue efforts
    to address the situation through its own
    management by terminating, disciplining,
    or at least counseling some individual
    mechanics whom it believed were
    responsible for the claimed slowdown./7
    IAM also argued that the improvement
    could be explained, at least in part, by
    the recent actions that United took
    against a rival union’s/8 website which
    had been attacking the IAM and expressly
    calling for a work slowdown among United
    mechanics.
    IAM moved to vacate the TRO on grounds
    that it did not comply with the
    procedural requirements of the Norris-
    LaGuardia Act ("NLGA"). On December 7,
    2000, the court denied IAM’s motion, but
    dissolved the TRO sua sponte, stating
    that there was some proof that the
    issuance of the TRO "caused some activity
    on the part of the Union, but at the same
    time it caused a reaction by those
    persons who may, as has been alleged, be
    beyond the control of the Union." The
    Court also found that "at this point . .
    . neither party should perceive any
    advantage by the issuance of the [TRO],"
    and that "the compulsive reasons for the
    issuance of the [TRO] have now subsided .
    . . ." The court then stated:
    I think the urgency of the [TRO] in the
    court’s mind was because of the pending
    travel over the Thanksgiving holidays and
    also what the court perceived, based upon
    the information the court had then, was
    perhaps some activity on the part of the
    Union if not actively attempting to
    curtail that activity, maybe in a
    somewhat covert manner to encourage that
    activity. I think that the allegation of
    that activity has clearly been dissipated
    at this point in the court’s mind based
    upon the submissions of the parties that
    I have received since the order has been
    in effect . . . . [B]ased upon the
    information that I have received, the
    [TRO] has been somewhat ineffective in
    requiring the mechanics to do their jobs
    appropriately without false claims of
    safety issues in order to undermine the
    ability of United to service its
    customers.
    The court noted that a hearing on
    United’s motion for a preliminary
    injunction was set for December 13, and
    it opined that not having the TRO in
    effect during that period would "give the
    court an opportunity to view without the
    order in place the activities of the
    parties," thereby providing "some
    guidance as to its findings as to whether
    or not a preliminary injunction should
    issue."
    After hearing oral argument from the
    parties, the district court denied
    United’s motions for contempt and for a
    preliminary injunction without written
    opinion. In denying the motion for
    contempt, while the court found that the
    Union did not "immediately do all actions
    which ultimately were done," and that the
    manner of its initial posting of the TRO
    "perhaps was not the most effective way
    to garner acquiescence and compliance
    with the order," the court found that
    these failings did not rise to the level
    of contempt and that the Union eventually
    "complied not only with the intent but
    with the letter of the [TRO] by taking
    those actions which they thought were
    prudent and escalating those actions when
    it appeared that they were not
    effective." The court also stated that
    "the facts in this case have convinced
    the court that there are some members of
    [IAM]’s union who despite their best
    efforts have continued to, and perhaps
    will continue to, act inappropriately and
    to do these job actions which are not
    proper." In denying the preliminary
    injunction, the court stated:
    I think that there is somewhat of a mob
    mentality out there somewhere where
    people believe as long as we act in
    concert and groups we are all safe by the
    fact that no one can be identified,
    singled out, and held to pay the
    consequences of their actions . . . .
    [T]hose persons being identified and
    subjected to immediate consequences I
    think is the best way and maybe the only
    way to insure that the majority of the
    members of the union continue to act
    appropriately in this case. I find that
    this is a much more effective way to
    control thatmembership than it is for the
    court to issue an order telling people to
    do what they are legally obligated to do
    under the various statutes that control
    this situation.
    United has appealed the district court’s
    denial of its motion for preliminary
    injunction, arguing that the district
    erred both legally and factually in
    refusing the injunction on the ground
    that United could more effectively end
    the slowdown by disciplining and/or
    terminating those individual mechanics
    responsible. IAM argues that the district
    court correctly perceived that the NLGA
    precluded the injunction unless it would
    have been the "sole, effective means" of
    solving the problem, and that the court
    correctly found that such was not the
    case here. In addition, IAM argues that
    sec.sec. 106, 107(a), and 108 of the NLGA
    barred the injunction, because there is
    no "clear proof" that the IAM authorized,
    encouraged or ratified the slowdown, and
    because United did not make "every
    reasonable effort to resolve the dispute"
    before seeking the injunction.
    DISCUSSION
    In reviewing the denial of a preliminary
    injunction, we review the district
    court’s findings of fact for clear error,
    its balancing of the factors for a
    preliminary injunction under the abuse of
    discretion standard, and its legal
    conclusions de novo. See Kiel v. City of
    Kenosha, 
    236 F.3d 814
    , 815 (7th Cir.
    2000) (citation omitted); Teamsters Local
    Unions Nos. 75 and 200 v. Barry Trucking,
    Inc., 
    176 F.3d 1004
    , 1011 (7th Cir.
    1999). We accord substantial deference to
    the trial court’s decision because we
    "recognize the advantage of the trial
    court’s proximity to the evidence." See
    Teamsters, 
    176 F.3d at 1011
    . Therefore,
    we will not find a district court’s
    factual finding clearly erroneous if it
    is "plausible in light of the record
    viewed in its entirety," even if we would
    have "’weighed the evidence differently’
    and reached the opposite conclusion." See
    Air Line Pilots Ass’n Int’l v. United Air
    Lines, Inc., 
    802 F.2d 886
    , 891 (7th Cir.
    1986) (citation omitted) ("ALPA").
    However, the lower court necessarily
    abuses its discretion when it commits an
    error of law, see MacDonald v. Chicago
    Park District, 
    132 F.3d 355
    , 357 (7th
    Cir. 1997) (citation omitted), and a
    decision to deny a preliminary injunction
    that is premised on an error of law is
    entitled to no deference and must be
    reversed. See, e.g., Delta Air Lines,
    Inc. v. Air Line Pilots Ass’n Int’l, 
    2001 WL 42399
    , *5 (11th Cir. 2001) (citations
    omitted).
    The RLA was enacted, among other
    reasons, "[t]o avoid any interruption to
    commerce or to the operation of any
    carrier engaged therein," and "to provide
    for the prompt and orderly settlement of
    all disputes concerning rates of pay,
    rules, or working conditions." 45 U.S.C.
    sec. 151a. The intent of the RLA is "to
    encourage collective bargaining by the
    parties ’in order to prevent, if
    possible, wasteful strikes and
    interruptions of interstate commerce.’"
    ALPA, 
    802 F.2d at 895
     (quoting Detroit &
    Toledo Shore Line R.R. v. United Transp.
    Union, 
    396 U.S. 142
    , 148 (1969) (footnote
    omitted)). To effectuate these purposes,
    the RLA imposes a substantive duty upon
    "all carriers, their officers, agents and
    employees to exert every reasonable
    effort to make and maintain agreements .
    . . and to settle all disputes . . . in
    order to avoid any interruption to
    commerce or to the operation of any
    carrier growing out of any dispute
    between the carrier and the employees
    thereof." 45 U.S.C. sec. 152, First. This
    duty runs both to management and to
    labor, and it has been described as the
    "heart" of the RLA. See Brotherhood of
    R.R. Trainmen v. Jacksonville Terminal
    Co., 
    394 U.S. 369
    , 377-78 (1969).
    Moreover, the duty to exert every
    reasonable effort to make and maintain
    agreements is a substantive legal duty
    which is enforceable by the courts.
    Chicago & N.W. Ry. Co. v. United Transp.
    Union, 
    402 U.S. 570
    , 577 (1971) ("[W]e
    think it plain that [45 U.S.C. sec. 152,
    First] was intended to be more than a
    mere statement of policy or exhortation
    to the parties; rather, it was designed
    to be a legal obligation, enforceable by
    whatever appropriate means might be
    developed on a case-by-case basis.")
    The RLA sets forth a detailed sequence
    of steps that carriers and their
    employees (or their employees’
    representatives) must follow in
    negotiating CBAs. First, the party
    seeking a change in rates of pay, rules
    or working conditions must give notice
    and confer with the other party. 45
    U.S.C. sec. 156. If the parties remain
    unable to resolve their dispute after
    this conference, either or both of them
    may seek mediation by the NMB. See 45
    U.S.C. sec. 155. If the mediation fails
    to produce agreement, the NMB must
    attempt to persuade the parties to submit
    to binding arbitration. If either or both
    of the parties rejects the offer of
    arbitration and the dispute threatens
    "substantially to interrupt interstate
    commerce to a degree such as to deprive
    any section of the country of substantial
    transportation service," the NMB must
    contact the President who may then create
    an emergency board to "investigate and
    report respecting such dispute." 45
    U.S.C. sec. 160. If the NMB releases the
    parties from mediation before an
    agreement has been reached, the RLA
    imposes a 30-day "cooling-off" period
    upon the parties. Throughout this entire
    lengthy negotiation process, carriers and
    unions are required to maintain the
    status quo with respect to rates of pay,
    rules, and working conditions. See 45
    U.S.C. sec.sec. 155, 156. The status quo
    provisions are "central" to the RLA’s
    design, see Shore Line, 
    396 U.S. at 150
    ,
    and they "must be read in conjunction
    with the implicit status quo requirement
    in the obligation imposed upon both
    parties by [sec.152], First ’to exert
    every reasonable effort’ to settle
    disputes without interruption to
    interstate commerce" as part of an
    "integrated, harmonious scheme for
    preserving the status quo from the
    beginning of a major dispute through the
    final 30-day ’cooling-off’ period." 
    Id. at 151, 152
    . If either side unilaterally
    alters the status quo during the
    bargaining andmediation process, a court
    may issue an injunction to put a stop to
    that party’s illegal self-help and to
    restore the status quo, and it may do so
    even without the traditional showing of
    irreparable injury to the other party.
    See Consol. Rail Corp. v. Ry. Labor
    Executives’ Ass’n., 
    491 U.S. 299
    , 303
    (1989). This rule authorizes courts to
    enjoin not only strikes but also "union
    conduct . . . which has the consequences
    of a strike," such as refusal of
    overtime, slowdowns, and sit-ins. See
    generally ALPA, 
    802 F.2d at 906
     (citation
    omitted).
    However, when a carrier seeks an
    injunction against a union, "a court must
    look not only to the RLA but also to the
    NLGA to determine whether the court has
    jurisdiction." See Delta Air Lines, 
    2001 WL 42399
     at *4. As a general rule the
    NLGA strips courts of jurisdiction to
    enter injunctions against labor unions in
    cases growing out of labor disputes,
    "express[ing] a basic policy against the
    injunction of activities of labor
    unions." See Int’l Ass’n of Machinists v.
    Street, 
    367 U.S. 740
    , 772 (1961). The
    NLGA also provides that "no injunction or
    temporary restraining order shall be
    issued on account of any threat or
    unlawful act excepting against the . . .
    organization making the threat or commit
    ting the unlawful act or actually
    ratifying the same after actual knowledge
    thereof," 29 U.S.C. sec. 107(a), and that
    "[n]o . . . organization participating or
    interested in a labor dispute shall be
    held responsible or liable . . . for the
    unlawful acts of individual officers,
    members, or agents, except upon clear
    proof of actual participation in, or
    actual authorization of, such acts, or of
    ratification of such acts after actual
    knowledge thereof." 29 U.S.C. sec. 106.
    In seeking to accommodate the conflicting
    provisions of the RLA and the NLGA, the
    Supreme Court has held that where a
    challenged action violates specific
    provisions of the RLA (such as the status
    quo provision of 45 U.S.C. sec. 152,
    First), "the specific provisions of the
    [RLA] take precedence over the more
    general provisions of the [NLGA]," see
    Pittsburgh & Lake Erie R.R. Co. v. Ry.
    Labor Executives’ Ass’n, 
    491 U.S. 490
    ,
    513 (1989) (quotation omitted); see also
    Chicago & North Western Ry., 
    402 U.S. at 581
    ; Brotherhood of R.R. Trainmen v.
    Chicago River & Indiana R.R. Co., 
    353 U.S. 30
    , 41-42 (1957), and courts can
    issue injunctions to enforce the RLA
    provisions at issue notwithstanding the
    NLGA./9 In other words, the Court has
    carved out an exception from the NLGA’s
    general prohibition on injunctive relief
    against union activity for violations of
    specific provisions of the RLA. However,
    the Court has stated that this exception
    is a limited one which applies only if an
    injunction is the "only, practical,
    effective means of enforcing the duty to
    exert every reasonable effort to make and
    maintain agreements," see Chicago & North
    Western Ry., 
    402 U.S. at 583
    , or if "that
    remedy alone can effectively guard the
    plaintiff’s right." 
    Id. at 582
     (quotation
    omitted).
    United argues that the district court
    misapplied the law and abused its
    discretion in denying its motion for a
    preliminary injunction under the RLA.
    First, United contends that since the
    court found that some of its mechanics
    were engaging in a concerted job action
    (that is, a deliberate slowdown) during
    the mediation process, United was
    entitled under the RLA to an injunction
    ordering the union to make every
    reasonable effort to stop the slowdown
    even if it could not be determined
    whether the injunction against the union
    would have been entirely effective in
    ending it. Therefore, United asserts that
    the district court erred as a matter of
    law when it decided not to issue the
    injunction solely on the ground that it
    would be more "effective" for United to
    address the problem by disciplining or
    firing the individual workers who were
    responsible for the slowdown. IAM
    counters that, given the proscriptions of
    the NLGA, status quo injunctions can only
    issue against a union when the injunction
    would be the "only practical, effective
    means" of enforcing the RLA, and that the
    district court was therefore required to
    inquire into the effectiveness of the
    injunction, and to deny it once it
    legitimately concluded that United could
    more effectively address the problem
    through management efforts.
    We agree with United. While it is true
    that, given the goals of the NLGA, courts
    should hesitate to issue an injunction
    unless it is the "sole effective means,"
    to address the RLA violation, IAM cites
    no authority (nor have we found any) for
    the proposition that a district court
    must deny a preliminary injunction
    against a recognized violation of a
    specific provision of the RLA by union
    members if it determines that the
    employer could "more effectively" curb
    the violation by directly disciplining or
    terminating individual employees. Indeed,
    such a suggestion runs counter to the
    spirit of the RLA’s status quo
    provisions. As noted, those provisions
    impose an affirmative legal duty upon
    both employers and unions alike--which is
    enforceable by the courts--to preserve
    the status quo during the bargaining and
    mediation process imposed by the RLA. A
    union has the affirmative duty under the
    status quo provisions of the RLA to exert
    every reasonable effort to prevent or
    discourage a strike or a concerted work
    action like the slowdown in this case.
    See, e.g., Delta Air Lines, 
    2001 WL 42399
    at *6; see generally Shore Line, 
    396 U.S. at 152-53
    . Once a court determines that
    such a concerted work action is occurring
    in violation of the RLA, an injunction
    can issue ordering the union to observe
    its statutory duty by trying to stop it.
    See, e.g., Delta 
    2001 WL 42399
     at *6.
    Whether United can diminish or even stop
    the work slowdown through its own actions
    has nothing to do with the IAM’s
    enforceable duty to do everything
    reasonable to end it. To hold otherwise
    would be to deny the union’s independent
    obligations under the RLA. This is not to
    say, however, that the limitations placed
    upon the issuance of injunctions against
    unions which violate their status quo
    obligations under the RLA cases are
    insubstantial. It remains true that
    courts should only enjoin such violations
    when the injunction would be the "sole
    practical, effective means of enforcing
    the duty to exert every reasonable effort
    to make and maintain agreements." This
    clearly implies that where there are
    other effective means available to
    accomplish that end, injunctions should
    not issue. However, requiring United to
    take efforts to end the slowdown would
    not be an "effective means" of enforcing
    IAM’s duty to "exert every reasonable
    effort to make and maintain agreements";
    rather, it would be requiring United to
    assume IAM’s duty altogether. Indeed, if
    we were to accept the premise that a
    carrier’s ability to fire or discipline
    individual employees is an "effective"
    remedy for a union’s status quo
    violations, a status quo injunction could
    never issue against a union, since in
    virtually every case an employer
    presumably could take some such measures.
    Such an interpretation would eviscerate
    the status quo provisions of the RLA.
    Therefore, we find that the district
    court’s decision in this case was not
    justifiable, much less mandated, by the
    NLGA. To the extent that the district
    court may have concluded otherwise, it
    erred as a matter of law./10
    For similar reasons, we also reject
    IAM’s argument that sec. 8 of the NLGA
    bars United from seeking injunctive
    relief in this case. That section
    provides:
    No restraining order or injunctive
    relief shall be granted to any
    complainant who has failed to comply with
    any obligation imposed by law which is
    involved in the labor dispute in
    question, or who has failed to make every
    reasonable effort to settle such dispute
    either by negotiation or with the aid of
    any available governmental machinery of
    mediation or arbitration.
    29 U.S.C. sec. 108. This section is
    applicable to injunctions sought by
    carriers against unions under the status
    quo provisions of the RLA. See generally
    ALPA, 
    802 F.2d at 900, 905-06
    . By its
    terms, this "clean hands" provision
    precludes a carrier involved in a labor
    dispute with a union from obtaining
    injunctive relief when the carrier has
    either: (1) violated a legal obligation
    with respect to the labor dispute in
    question; or (2) failed to make every
    reasonable effort to settle the labor
    dispute either through negotiation,
    mediation, or arbitration. See
    Brotherhood of R.R. Trainmen Enterprise
    Lodge, No. 27 v. Toledo, P. & W.R.R., 
    321 U.S. 50
     (1944) (holding that, while the
    RLA does not require either party to a
    major labor dispute to submit to arbitra
    tion, a carrier who refuses this
    available avenue for settlement cannot
    obtain injunctive relief under the status
    quo provisions).
    IAM argues that United did not make
    every "reasonable effort to settle" the
    dispute in this case, claiming that
    United made virtually no attempt to
    resolve the slowdown through negotiations
    with IAM before it filed suit. IAM claims
    that Studdert’s November 10 letter to
    Ford was the first and only time that
    United mentioned the problem to IAM
    officials before seeking the injunction,
    and that the letter was in fact sent
    immediately after United had thanked IAM
    for "keeping the lid on" and averting
    serious work actions during a tense
    period of negotiations. United disputes
    these assertions, but we need not credit
    United’s version of the story to dispose
    of IAM’s claim. Section 8 requires a
    party to a labor dispute to "exert every
    reasonable effort" to settle the labor
    dispute in question (through negotiation,
    mediation or arbitration) before seeking
    to enjoin an action by the other party
    which relates to the dispute. It does not
    require a party who is already engaging
    in good-faith effort to settle the labor
    dispute through negotiation, mediation,
    or arbitration to "exert every reasonable
    effort" to prevent or end an unlawful
    strike or work action before seeking
    judicial relief. Indeed, requiring a
    carrier to seek a negotiated solution
    before moving to enjoin an illegal work
    action would enable unions to use such
    actions to extort concessions from the
    carrier during the negotiation process.
    Such a result would render the union’s
    duty under 45 U.S.C. sec. 152, First a
    nullity, and would run directly contrary
    to the policy rationales of the RLA’s
    status quo provisions. If IAM had
    demonstrated that United had either
    violated its own status quo obligations
    (or some other duty under the labor laws)
    or had failed to pursue all of the
    available channels of negotiation,
    mediation, and arbitration provided under
    the RLA, then it would have a stronger
    case for barring the injunction under
    sec. 8 of the NLGA. However, as IAM has
    not made any such contention, we must
    reject its argument under sec. 8./11
    Moreover, it seems clear in this case
    that an injunction would be the "sole,
    effective means" of enforcing the IAM’s
    duties under the status quo provisions of
    the RLA. The district court concluded
    that a number of United mechanics were
    engaging in a deliberate and unlawful
    slowdown (or that a number of mechanics
    were "do[ing] job actions which are not
    proper" and acting "in concert" or in a
    "mob mentality"). This unilateral resort
    to self-help on the part of union members
    puts severe economic pressures on United,
    thereby undermining its bargaining
    position during the period of negotiation
    and mediation. This is precisely the kind
    of action that the RLA status quo
    provisions seek to prevent, and we cannot
    conclude that other remedies, short of an
    injunction, would be effective in doing
    so. Cf. Int’l Ass’n of Machinists &
    Aerospace Workers v. Transportes Aereos
    Mercantiles Pan Americandos, S.A., 
    924 F.2d 1005
    , 1011 (11th Cir. 1991).
    IAM also argues that sec.sec. 6 and 7(a)
    of the NLGA prohibit the issuance of a
    preliminary injunction against it.
    Section 7 limits the jurisdiction of the
    federal courts to issue injunctions in
    cases involving or growing out of a labor
    dispute, and subsection (a) provides in
    part that "no injunction or temporary
    restraining order shall be issued on
    account of any threat or unlawful act
    excepting against the person or persons,
    association, or organization making the
    threat or committing the unlawful act or
    actually authorizing or ratifying the
    same after actual knowledge thereof." 29
    U.S.C. sec. 107(a). Section 6 provides in
    part that "no association or organization
    participating or interested in a labor
    dispute shall be held responsible or
    liable in any court of the United States
    for the unlawful acts of individual offi
    cers, members, or agents, except upon
    clear proof of actual participation in,
    or actual authorization of, such acts, or
    of ratification of such acts after actual
    knowledge thereof." 29 U.S.C. sec. 106.
    In ALPA, we ruled that a carrier could
    not establish that a union had committed
    a status quo violation by means of an
    orchestrated "sick-out" without proving
    by clear and convincing evidence that the
    union had promoted the alleged sick-out,
    and that statistical evidence showing
    that pilots had taken twice their usual
    number of sick days during the relevant
    time period was insufficient by itself to
    implicate the union under this "clear proof"
    standard. See ALPA, 
    802 F.2d at 905-06
    .
    IAM argues that, even if some United
    mechanics were engaging in a work
    slowdown, United has not offered "clear proof"
    that IAM authorized or ratified the
    slowdown. IAM maintains that it had
    repeatedly counseled its mechanics not to
    engage in any job action, and that many
    of the "work safe" bulletins and flyers
    that United offered as evidence of a
    concerted slowdown were written not by
    IAM but by "strident opponents" of IAM
    (i.e., by mechanics or others who were
    sympathetic with a rival union and
    hostile to IAM). IAM also asserts that
    any "work safe" language appearing in
    those bulletins that it did publish meant
    only what it said and was intended
    innocently. For example, IAM claims that
    the "work safe" language contained in the
    District 141-M bulletin of October 13 was
    inserted in response to United’s concerns
    regarding recent workplace accidents.
    Moreover, IAM contends that the increases
    in write-ups and other maintenance-
    related anomalies experienced by United
    could have been caused by only a "few
    dissident mechanics."
    We find that United has offered enough
    "clear proof" of IAM’s involvement in the
    work slowdown to satisfy the standard of
    sec. 6. While it is true that statistics
    alone will not provide clear proof of a
    union’s involvement in a work action,
    United did not rely on statistical
    evidence alone. In fact, it presented
    evidence of the kind that we have
    expressly suggested would establish a
    union’s responsibility for authorizing or
    ratifying a work action under sec. 6. See
    ALPA, 
    802 F.2d at 905
    . United produced a
    number of IAM bulletins which included
    prominently displayed exhortations to
    "work safe." Moreover, United produced
    testimony from some of its maintenance
    officials that a union’s suggestions to
    its mechanics to "work safe" or to "work
    by the book" are commonly recognized
    signals among union mechanics for a work
    slowdown. IAM has not challenged this
    testimony, and courts have found similar
    language to be "codes" for job actions.
    See, e.g., The New York Times Co. v.
    Newspaper & Mail Deliverers Union, 
    740 F. Supp. 240
    , 244 (S.D.N.Y. 1990) (finding
    that a union chapel chairman’s directive
    to members to "adhere to strict
    contractual requirements in making their
    deliveries" was a call for a "slowdown
    from normal operations"); Tex. Int’l
    Airlines, Inc. v. Air Line Pilots Ass’n
    Int’l, 
    518 F. Supp. 203
    , 210-11 (S.D.
    Tex. 1981) (finding that council
    chairman’s letter to union members
    advising them to "adhere to company
    policies, and contractual agreements";
    "not to neglect even the most minor write
    ups"; . . . and "to check every item on
    the checklists" was sent with the
    understanding that pilots would interpret
    it as a call for a slowdown). Further,
    while IAM claims that it did not publish
    many of these bulletins, it admits to
    publishing some of them (for example, the
    District Lodge 141-M bulletin published
    on October 13, and the October 19
    bulletin issued by Local Lodge 2294 in
    Indianapolis). IAM offers no satisfying
    explanation for why these bulletins
    included--indeed, trumpeted--the message
    to WORK SAFE! in the context of blaming
    United for the lack of progress in the
    negotiations or of criticizing United for
    its recent oppressive management actions.
    Nor does IAM explain why the language
    telling mechanics to "work safe" was the
    only language written in bold face,
    underlined, or in all capital letters.
    While some of these bulletins also
    contain statements urging members not to
    "engage in any job action," such
    statements are dwarfed by the messages to
    "work safe," leaving the clear impression
    that the relatively inconspicuous
    statements discouraging a slowdown were
    not meant to be taken at face value.
    Given the context in which the "work
    safe" messages appeared and the prominent
    nature of their display, their obvious
    intent was to urge mechanics to engage in
    a work slowdown in response to the
    impasse in negotiations. In addition,
    given that IAM does not deny that such
    language can serve as a code for a
    slowdown, we find it difficult to believe
    that IAM would have included such
    language in the context of bulletins
    regarding negotiations (especially at a
    time when it claims that bulletins
    bearing the same code language were being
    distributed by dissident mechanics as a
    call for a slowdown) unless it intended
    to signal the mechanics to engage in a
    slowdown.
    In addition, although it denies
    responsibility for their authorship, IAM
    does not satisfactorily explain how even
    more suspicious bulletins came to be
    distributed in three United maintenance
    centers in late October or early
    November, at least one of which was
    placed in a locked IAM bulletin board.
    These bulletins were issued under the
    headings "Negotiations 2000," "Millennium
    Negotiations," and "Lodge 1781 Strike
    Committee,"/12 and they each urged
    mechanics (in virtually identical
    language) to clean their boxes and tools
    "daily" and to "shut down and fix"
    anything that isn’t safe, in keeping with
    the "safety first ideal." This is exactly
    the kind of evidence that we have
    suggested could provide "clear proof" of
    a union’s authorization of a slowdown.
    See ALPA, 
    802 F.2d at 905
     (suggesting
    that statistical evidence of a sickout
    plus, inter alia, "a notice posted on a
    union bulletin board" could indicate
    union involvement in a sickout under sec.
    6) (discussing Pan American World
    Airways, Inc. v. Independent Union of
    Flight Attendants, 93 Lab.Cas. (CCH)
    para. 13,307, 20,035 (S.D.N.Y. July 20,
    1981) (finding evidence of union
    involvement in a sickout sufficient to
    support an injunction where, inter alia,
    the union did not take sufficient steps
    to disavow a planned sickout by its
    members and where an unsigned notice
    reporting on the negotiations and
    indirectly calling for the sickout was
    posted on a locked union bulletin board
    to which only the union had access)).
    When this evidence is considered
    alongside United’s compelling statistical
    evidence, which suggests that the work
    slowdown began to abate just as IAM
    stepped up its efforts to discourage it
    in late November, IAM’s involvement in
    the slowdown becomes all the more
    apparent. Thus, while it is not clear
    that the district court found that IAM
    had not authorized the slowdown,/13
    even if it did, we would find such a
    finding clearly erroneous.
    Finally, IAM argues that even if the
    NLGA did not dictate the result reached
    by the district court, the court
    nevertheless had the discretion under
    traditional principles of equity to deny
    the injunction--notwithstanding the
    provisions of the RLA--if it found that
    the injunction would not effectively
    provide United with the relief it sought.
    See, e.g., Virginian Ry. Co. v. Sys.
    Fed’n No. 40, 
    300 U.S. 515
    , 550 (1937).
    IAM contends that the district court
    found that the injunction would be
    ineffective after carefully considering
    the record evidence, which suggested that
    the TRO had been relatively ineffective
    in restoring the status quo and that the
    situation had not worsened appreciably
    for United once the TRO was dissolved.
    Therefore, IAM maintains that the
    district court’s factual finding that the
    injunction would be similarly ineffective
    was not clearly erroneous, and must be
    affirmed. We reject this argument. The
    record does not support an inference that
    the injunction would be ineffective. To
    the contrary, the statistical evidence
    before the district court suggested that,
    while the TRO did not succeed in bringing
    the rates of writeups, planes held out of
    service, and maintenance-related
    cancellations and delays to historical
    levels, it did have a substantial
    positive effect after the IAM sought to
    implement it more aggressively. We find
    IAM’s contention that this positive
    effect was due solely to United’s belated
    efforts to counsel and to take
    disciplinary action against offending
    mechanics unpersuasive in light of
    United’s submissions that it did take
    such actions earlier, and that such
    actions had little effect. Moreover, even
    assuming that United’s management efforts
    were partly responsible for the positive
    trend (which, we note, the district court
    did not expressly find), we find no
    plausible basis for the conclusion that
    an injunction against the union would not
    have an additional positive effect. Even
    if we were to agree that United could
    achieve favorable results by disciplining
    individual mechanics, the evidence
    suggests that it could achieve even more
    favorable results if, in addition, the
    injunction were in place. Given all of
    this, and considering that in issuing the
    TRO the district court found that the
    traditional equitable factors--including
    the balance of hardships and the public
    interest--weighed in favor of granting
    the injunction and that it never
    expressly found to the contrary, we see
    no equitable reason to withhold
    injunctive relief in this case./14
    Moreover, we note that the district
    court did not expressly find that the
    injunction would be wholly ineffective.
    Rather, in dissolving the TRO it found
    that the TRO had been "somewhat
    ineffective," and in denying United’s
    motion for a preliminary injunction it
    found merely that it would be "more
    effective" for United to try to resolve
    the problem through management. This
    latter finding seems to be the basis for
    the court’s decision, and the court
    unfortunately provided very little
    support for the finding. In any event, we
    hold that the court misapplied the law in
    basing its decision on such a finding.
    The court concluded that some United
    mechanics were engaging in a work
    slowdown in violation of the RLA, and as
    we have already demonstrated, the
    evidence established IAM’s involvement in
    the illegal slowdown. As we have noted,
    under these circumstances a court may
    issue an injunction against a union as
    the "sole, effective means" of enforcing
    the union to observe its obligations
    under the RLA’s status quo provisions,
    and a carrier’s efforts to solve the
    problem through management are no
    substitute for judicial enforcement of
    the union’s independent obligations. See
    National Airlines, Inc. v. Int’l Ass’n of
    Machinists and Aerospace Workers, 
    416 F.2d 998
    , 1006 n.7 (5th Cir. 1969)
    (stating that "[t]he primary
    responsibility for ending [a] strike [in
    violation of the RLA] rest[s] in the
    district court"). Therefore, by denying
    an injunction against IAM’s illegal job
    action solely on the grounds that the
    problem could be more effectively
    addressed by United, the court denied
    United a judicial remedy to which it was
    entitled under the RLA and erred as a
    matter of law.
    CONCLUSION
    We have considered IAM’s other
    arguments, and find them meritless. For
    the foregoing reasons, we REVERSE the
    decision of the district court, and REMAND
    with instructions to enter the
    preliminary injunction against IAM and to
    fix a date for trial on the issue of a
    permanent injunction in as short a time
    as is reasonably possible. REVERSED and
    REMANDED.
    /1 A maintenance "write-up" is a written record by
    a mechanic of any item on an aircraft that may
    have a defect or a condition requiring further
    inspection or repair. Some write-ups identify
    serious defects that may affect airworthiness and
    therefore must be repaired immediately. Others
    involve merely trivial or cosmetic defects, such
    as broken tray tables or scratched paint, which
    can be repaired at a later time.
    /2 A "cycle time" is the time that it takes to
    perform a scheduled maintenance check.
    /3 The number of aircraft out of service for an
    unscheduled maintenance check is a function of
    two factors: the number of maintenance write-ups,
    and the amount of time that it takes the mechan-
    ics to repair the defects.
    /4 According to an economist retained by United, the
    odds that the increases in cancellations and
    delays could be caused by random, coincidental
    behavior by United’s mechanics were less than one
    in a trillion.
    /5 IAM denies that any of its local lodges actually
    issued these bulletins or memos, and claimed that
    they were issued either by individual "dissident"
    union members without authorization, or by other
    individuals who were hostile to the IAM and
    sympathetic to a rival union that had been gain-
    ing strength at United and that was trying to
    replace IAM. In his deposition, United Vice
    President of Line Maintenance William Norman
    conceded that he did not know whether they were
    actually published or produced by IAM lodges or
    union officials. Norman Dep. at 85-6.
    /6 United claims that IAM posted the TRO only on
    their websites, that they did not direct member
    mechanics to cease all slowdown activity and all
    communications encouraging such activity upon
    pain of fine, suspension or other sanction by
    IAM, that the website bulletin that IAM did
    release implicitly encouraged continuation of the
    slowdown (by stressing the continued need for
    mechanics to observe all safety regulations), and
    that the two local lodge officers who issued
    notice of the TRO expressed contempt for it. For
    its part, IAM claims that it personally served
    every mechanic with a copy of the TRO within days
    of its issuance, that it immediately posted
    notice of the TRO on its website and on union-
    maintained bulletin boards, that its website
    notice did urge compliance with the TRO (and that
    its reference to the district court’s own lan-
    guage stating that the TRO was not meant to
    impede the mechanics’ compliance with safety
    regulations was not a signal for a further slow-
    down), and that Union representatives notified
    mechanics at stations throughout the county of
    the need to comply with the TRO.
    /7 IAM contends that United never took any such
    actions until after the November 27 conference
    with the court. IAM claims that the November 10
    letter from Studdert to Ford was the first time
    that United had accused IAM of encouraging a
    slowdown (indeed, at a meeting one week before
    the letter, IAM claims that United complimented
    IAM for "keeping the lid on," or for preventing
    job actions by its members during the tense
    negotiations). IAM also claims that United gave
    it specific evidence and the names of individual
    mechanics engaged in the slowdown only after the
    November 27 conference, and that IAM later dis-
    covered that almost none of those individuals had
    been disciplined or even counseled by United
    before United filed suit. United claims that it
    did discipline hundreds of employees (and fired
    some) long before filing suit, and that these
    efforts had little effect in curbing the slowdown
    until IAM finally got serious about implementing
    the TRO ). It also claims that it had several
    conversations with IAM about the problem before
    the Studdert letter (noting that the letter
    references earlier conversations between United
    and IAM about the slowdowns).
    /8 IAM noted that mechanics who supported the rival
    union had called for work slowdowns and refusals
    to work overtime publicly and in writing immedi-
    ately after United announced its plans to acquire
    U.S. Airways (a decision vigorously opposed by
    many United mechanics), and criticized IAM for
    refusing to do the same. Further, the mechanics
    supportive of the rival union staged what United
    believed was a "sick out" in several locations
    immediately after July 12. After United fired 11
    of these employees, and disciplined 11 others,
    the sick out ended.
    /9 However, when a carrier seeks to enjoin a strike
    against a union under the status quo provisions
    of the RLA, the procedural provisions of the NLGA
    remain in effect. See Delta Air Lines, 
    2001 WL 42399
     at *7. For example, a carrier seeking an
    injunction against a union must put on live
    testimony with the opportunity for cross-examina-
    tion, see 29 U.S.C. sec. 107, or there must at
    least be some equivalent guarantee of the reli-
    ability of the evidence presented. See Delta,
    
    2001 WL 42399
     at *7. However, in this case the
    parties stipulated to submit their case to the
    district court on the written record (through
    affidavits and briefs) without livetestimony,
    Dec. 13 Trans. at 4, and IAM has not raised any
    issue of its right to cross-examination either
    here or below. Thus, the issue is waived.
    /10 The cases cited by IAM on this point do not
    compel a different conclusion. In Int’l Ass’n of
    Machinists v. Street, 
    367 U.S. 740
     (1961), the
    Court overturned a blanket injunction brought by
    railway union members to enjoin their union from
    violating the RLA by spending funds exacted from
    union members on political causes, where the
    injunction restrained the union from collecting
    any funds from the objecting members. The court
    held that, because this injunction was overbroad
    (that is, because the plaintiff’s rights could be
    effectively vindicated by a more narrowly tai-
    lored injunction) it was not the only effective
    remedy available, and was therefore impermissible
    under the NLGA. The Court remanded for the dis-
    trict court to impose a more narrowly tailored
    remedy, suggesting that a narrower injunction
    would be appropriate. In Chicago & North Western
    R.R. Co., 
    402 U.S. 570
     (1971), the court reversed
    a lower court’s determination that sec. 152,
    First was not a legal obligation enforceable
    against a union by injunction, and remanded for
    the lower court to determine whether a strike
    injunction sought by the carrier in that case was
    the "only practical, effective means" of enforc-
    ing that section of the RLA. Neither case stands
    for the proposition that a court must deny an
    injunction against an illegal work action if it
    appears that the carrier could more effectively
    address the problem through management.
    /11 We should note, however, that even if IAM had
    demonstrated some such action on United’s part,
    it still might not be able to block United from
    obtaining the injunction it seeks. We have not
    read sec. 8 of the NLGA as forming an absolute
    bar to injunctive relief against status quo
    violations when the party seeking the injunction
    has violated either its own status quo obliga-
    tions or some other legal obligation. See ALPA,
    
    802 F.2d at 901
    . Rather, we have "weigh[ed] the
    competing equities to determine whether applying
    section 8’s bar to injunctive relief would serve
    to further underlying purposes of both the RLA
    and the [NGLA]." In so doing, we have expressly
    noted that the imperatives of the RLA may over-
    ride sec. 8, and that a party’s lack of "clean
    hands" under sec. 8 "may be overcome by a balanc-
    ing of the interests, particularly where it is
    the public interest involved." See Illinois
    Central R.R. Co. v. Brotherhood of R.R. Trainmen,
    
    398 F.2d 973
    , 976 (7th Cir. 1968) (quotation
    omitted). While we do not decide the matter, we
    note that United could make a strong argument
    here that both the balancing of hardships and the
    public interest weigh in favor of the issuance of
    the injunction in this case, and that therefore
    the injunction could have been granted even if
    United had violated sec. 8 of the NLGA.
    /12 The latter bulletin bore a cartoon of a wolf and
    stated "Wolf, play it safe, negotiate," and it
    purported to be from a committee that IAM claims
    does not exist. Third Supp. Dec. of Ford at para.
    4. Steve Wolf was the former CEO of United (in
    the early 1990’s). Id.; Dec. 13 Trans. at 43.
    This arguably suggests that the "wolf" bulletin
    was created several years ago, and not in connec-
    tion with the events at issue in this case.
    Moreover, as IAM notes, United Vice President of
    Line Maintenance William Norman admitted in his
    deposition that he did not know whether IAM
    actually published this bulletin, or when it was
    published. Norman Dep. at 81-82. However, even
    assuming that this bulletin was published in the
    early 1990’s, IAM has not explained how it came
    to be re-circulated in October and November of
    2000, nor has it explained why a bulletin with a
    substantially identical message (and without any
    reference to Wolf) appeared simultaneously in a
    locked IAM bulletin board at another location.
    /13 IAM claims that in dissolving the TRO, the dis-
    trict court found that IAM was not responsible
    for the alleged slowdown when it stated that the
    initial "allegation" that the IAM was covertlyen-
    couraging the slowdown had "clearly been dissi-
    pated . . . ." However, read in context, this
    statement seems to indicate that the district
    court believed that IAM was no longer encouraging
    the slowdown (after the TRO had been issued), not
    that it never had encouraged it. Some statements
    that the court made during the December 13 hear-
    ing on the preliminary injunction do suggest that
    the court believed that certain union members
    were engaging in a wildcat work action, "despite
    [IAM]’s best efforts." However, it is far from
    clear that the court actually made a finding on
    this issue.
    /14 IAM argues that an injunction would not be the
    most effective means to "address conduct of
    mechanics engaged in safety sensitive work," to
    "address conduct that is intertwined with consti-
    tutionally protected speech," or to "address the
    problem of dissident mechanics." We are not
    persuaded. First, courts have enjoined illegal
    work actions undertaken under the guise of safe-
    ty, see, e.g., Long Island R.R. Co. v. Sys. Fed’n
    No. 156, 
    368 F.2d 50
    , 52 (2d Cir. 1966), and IAM
    offers nothing to suggest that courts could not
    frame injunctive orders carefully to ensure that
    legitimate safety inspections are not compro-
    mised. (Indeed, the district court in this case
    did just that with respect to the TRO). In
    addition, enjoining a union from encouraging
    illegal job actions (or forcing it to discourage
    such action) during the limited period of negoti-
    ation and mediation would not intrude on consti-
    tutionally protected speech, as it would leave
    the union free to criticize the company’s bar-
    gaining position. Finally, we reject IAM’s argu-
    ment that the injunction would be ineffective
    because the slowdown was caused by dissident
    mechanics, both because we find that the evidence
    establishes IAM’s involvement, and because the
    statistical evidence strongly suggested that
    IAM’s efforts to implement the TRO in late Novem-
    ber were having an appreciable effect on the
    slowdown.
