This is an appeal from judgment in favor of a contractor claiming that a union engaged in improper secondary picketing in violation of federal law and breached the “no-strike” clause in the parties’ collective bargaining agreement. The union claims that its activity was aimed only at a nonunion contractor on the same project, and to the extent it affected the secondary contractor, it was protected as a sympathy strike implicitly allowed by the terms of their bargaining agreement. The union also challenges the district court’s damages award and the contractor cross appeals, claiming the court failed to include certain items in its calculation of prejudgment interest. We now affirm the district court’s decisions regarding each of the union’s claims, and reverse the court’s calculation of damages.
Background 1
This dispute stems from a picket line set up by Local 150 (“Local 150”) of the International Union of Operating Engineers (“IUOE”) in June 1992, at the National Gas Pipeline Company’s (“NGPL’s”) gas storage facility in Herscher, Illinois. In 1991, NGPL hired R.L. Coolsaet Company (“Coolsaet”), a union contractor, to repair a pipeline running into NGPL’s gas compressor at the Herscher facility. As a member of the Pipe Line Contractors As *653 sociation (“PLCA”), a national trade group, Coolsaet was at all relevant times a signatory to a national collective bargaining agreement (“National Agreement”) between the PLCA and the IUOE. Pursuant to this agreement, Coolsaet hired workers represented by Local 150, as well as workers represented by other craft unions, to perform the work at Herscher. Coolsaet worked in and around an 80-acre fenced-in area within the Herscher facility referred to as Station 201. In 1992, NGPL hired Haley Brothers, a local nonunion contractor, to perform water pipe installation work in the fields surrounding Section 201. At no time prior to the strike, however, did Coolsaet and Haley employees work in close proximity to each other.
On the morning of June 23, 1992, Local 150’s steward, Roger Seale, and one of its business agents, Gary Benefield, met at Station 201 and drove three miles to an area called Saffer 3, where Haley was then working. There, Benefield told one of Haley’s owners that its work should be performed by union labor and asked Haley to join Local 150. The owner refused. Soon after, John Filiatrault of NGPL arrived at Saffer 3 and told Benefield that Haley’s work was a “separate job, separate contract, separate system,” and that NGPL had the right to hire non-union contractors. Benefield responded that Haley’s presence at Herscher could result in union picketing. That afternoon, Roger Seale repeated Benefield’s warning to Coolsaet’s office manager.
The same day, in an effort to avert a strike, NGPL scheduled a meeting with union representatives but called it off after concluding that the dispute was between Coolsaet and its unions, not between the union and NGPL. After the meeting was canceled, Benefield called other craft unions representing Coolsaet employees to inform them that Local 150 would likely begin picketing the following day, June 24, in front of Station 201.
Station 201 had three gates: the Main Gate, which was used by anyone with business at the site, Gate 2, which was locked during this period, and Gate 3, which was used exclusively by Coolsaet employees. On the morning of June 24, Benefield set up pickets in the area where Haley had been working the day before, and in front of the Main Gate, which Haley occasionally used to retrieve supplies stored inside Station 201. Benefield also set up pickets in front of Gate 3, despite the union’s knowledge that only Coolsaet employees used that gate. The picket line included some Coolsaet employees.
Because none of its union employees would cross the picket line, Coolsaet’s operation was completely shut down from June 24 until July 7. On June 25, Michael Quigley, the Local 150 business agent in charge of the picketing activity, requested a meeting with NGPL and representatives from other unions to discuss his concern about Haley working at Herscher. NGPL’s manager, David Nightengale, informed Quigley that Haley had removed all of its supplies from Station 201 that day and asked why Local 150 continued to picket at that location instead of where Haley was actually working. Quigley responded that the union had the right to picket wherever it would be most effective.
The pickets remained in place in front of Station 201 from approximately 7:00 a.m. to 4:00 p.m. each day even though Haley no longer used either gate and Local 150 business agents did not know whether Haley was working on the site during those hours. During this period, Quigley told Coolsaet’s manager, Ryan Colonello, that as long as Haley was still on the job, the picketing would continue.
The National Agreement between the PLCA and IUOE contained a broad no-strike provision (Article IX(A)) which prohibited the union from engaging in any “strike slowdown, stoppage of work or any interference ... with the progress of the work” and prevented the employer from ordering any lockout of union workers. On July 25, 1992, Hailey Roberts, the di *654 rector of the PLCA, faxed a letter to Frank Hanley, president of the IUOE, informing him that Local 150 had set up a picket line at Herscher in violation of the no-strike clause in the National Agreement. On July 30, Howard Evans of the IUOE faxed Roberts’ letter to Bill Dugan, president of Local 150, along with a cover note stating: “I am sure you are aware that Article [IX] of the National Pipeline Agreement contains a no strike clause.” On July 2, Local 150 treasurer Joe Ward told Evans that “the picket line would be down on Monday [July 6].” When the strike continued on July 6, Evans faxed another letter ordering the removal of the picket line, which came down on July 7, 1992.
In September 1992, Coolsaet sued Local 150 for damages resulting from what it alleged was an illegal secondary picket in violation of the National Labor Relations Act (“NLRA”), 29 U.S.C. § 158(b)(4), and the Labor Management Relations Act (“LMRA”), 29 U.S.C. §§ 185 and 187. Coolsaet also claimed that Local 150 .breached the no-strike clause of the National Agreement.
Following a four day bench trial, the court determined that because Local 150 had intended to exert pressure on Coolsaet and NGPL, neutral or secondary employers, in an effort to remove Haley from the Herscher site, the union violated Section 8(b)(4) of the NLRA. Additionally, the court held that Local 150 breached the no-strike clause of the National Agreement. Based on the delay and increased cost Coolsaet incurred as a result of the strike, the court initially awarded the contractor $329,467 in damages. After additional briefing by the parties, the court awarded Coolsaet $105,221 in compounded prejudgment interest based on all of the contractor’s damages except those associated with equipment expenses on machines owned by Coolsaet.
Local 150 now appeals, claiming that it did not engage in any illegal secondary activity nor did it violate the National Agreement. The union also challenges the court’s damages and interest calculations. Coolsaet cross-appeals, claiming that the interest award improperly excluded equipment expenses and should have been higher.
Discussion
In reviewing the trial court’s decision, we examine any legal conclusions de novo,
Orix Credit Alliance v. Taylor Mach. Works, Inc.,
Unlawful Secondary Boycott
Section 303 of the LMRA provides a private cause of action for a party injured by union conduct defined as an unfair labor practice under Section 8 of the NLRA. 29 U.S.C. § 187. Section 8(b)(4), in turn, defines picketing as an unfair labor practice if “any object of that activity is to exert improper influence on secondary or neutral parties.”
International Union of Operating Engineers, Local 150, AFL-CIO v. NLRB,
*655 Where a union has a grievance with the terms and conditions of employment of a certain employer, (the “primary” employer), it must focus its picketing activity on that employer. The union may not exert pressure on an unrelated, “secondary” [or neutral] employer in order to coerce the secondary employer to cease dealing with the primary employer, thereby advancing the union’s goals indirectly.
Mawtz & Oren, Inc. v. Teamsters, Chauffeurs, and Helpers Union, Local No. 279,
The analysis of secondary activity is more complicated where the primary and secondary employers share a common work site.
Id.
at 762. In that situation, because it is difficult or impossible to target the primary employer without having a substantial effect on a secondary employer, Section 8(b)(4) has been interpreted to allow some foreseeable secondary impact so long as the union does not intend to enmesh the secondary employer in the dispute.
See Mautz & Oren,
The district court doubted whether Moore Dry Dock applied to this case because Haley’s and Coolsaet’s operations were more than a mile apart and thus the Herscher facility did not constitute a single work site. Even so, the court indicated that the Moore Dry Dock standards had not been met, particularly the limitations on the time and place of picketing. Ultimately, however, the court held that Moore Dry Dock was irrelevant because it found by a preponderance of the evidence that Local 150 intended to pressure secondary employers Coolsaet and NGPL in its effort to rid the Herscher facility of Haley. Essentially, the court concluded that one of the purposes of Local 150’s picket line was to disrupt Coolsaet’s operation by keeping its union employees from crossing it. This in turn would induce NGPL to either force Haley into joining the union or to kick the contractor off the premises in order to resume work.
The court based its conclusion on a number of factual findings: Local 150 set up pickets in front of Gate 3 despite its knowledge that only Coolsaet employees used that gate; the union used Coolsaet employees on its picket line; the continued picketing of Station 201 after Haley no longer stored material there; the union’s maintenance of the picket line without re *656 gard to whether Haley was on the site or not; the union’s failure to target Haley with its pickets and focus instead on areas where it knew Coolsaet was working; and, finally, the statements by Local 150 business agents made to representatives of Coolsaet and NGPL that the pickets would only come down if Haley was removed. Based on these findings, the court held that the union was “overtly exerting improper pressure on neutral employers [Coolsaet and NGPL]” in violation of Section 8(b)(4).
Local 150 now argues that the court’s legal conclusions were not supported by the facts and that many of the court’s key factual findings were incorrect. The union suggests that the court misinterpreted Local 150’s actions and failed to credit certain testimony which contradicted the court’s factual findings. Essentially, the union counters each key fact with its own version of events, reiterating what it argued before the district court.
However, the union has failed to overcome the considerable burden it bears in attempting to refute the district court’s factual findings.
See Air Line Pilots Ass’n, Int’l v. United Air Lines, Inc.,
Given these factual findings, we also agree with the court’s legal conclusion that Local 150 engaged in improper secondary activity. Even if this case is analyzed under
Moore Dry
Dock,
2
the court reasonably concluded that at least one of the union’s objectives was to pressure Coolsaet and NGPL into forcing Haley off the Herscher site. The court’s finding that Benefield and Quigley maintained the pickets at Station 201 without regard to where or when Haley was working supports the court’s conclusion that Local 150 had failed to satisfy two of
Moore Dry Dock’s
standards: that picketing be limited to the times and places the primary employer worked. This failure sets up a presumption of secondary intent which Local 150 has not rebutted.

The union argues that the statements it made to Coolsaet and NGPL were protected by the Supreme Court’s decision in
NLRB v. Servette,
While the line between permissible primary activity and unlawful secondary activity may be “more nice than obvious,”
Local 761, Elec. Workers v. NLRB,
Breach of the National Agreement
The union next argues that it did not breach the National Agreement because Coolsaet failed to exhaust contractual remedies and because the Agreement’s no-strike provision did not cover the kind of picketing at issue.
The trial court concluded that although Article IX(A) 3 of the National Agreement states that all disputes concerning the Agreement were to be arbitrated, Article IX(B) allows either party to opt out of the arbitration clause and go directly to court if the dispute involves a union strike or an employer lock-out. Article IX(B) provides in relevant part:
If the local union ... causes or promotes a strike, slowdown, work stoppage or any interference with the operation or progress of the work ... then the Employer ... may at its option declare the provisions of [the arbitration clause] inoperative and seek whatever remedy may be available from the National Labor Relations Board or any Federal or State court having jurisdiction over the matter.
The trial court decided that because Cool-saet chose to pursue its remedy in federal court, it had triggered Article IX(B) and did not need to arbitrate the dispute. 4
Local 150 now argues that Coolsaet never actually “declared” that the arbitration clause was inoperative, so it is still in effect and the employer is still bound by its requirements. We reject this formalistic assertion. Article IX(B) does not appear to require any specific deelara
*658
tion language and none should be inferred. It is hard to imagine a clearer declaration that the arbitration clause is inoperative than the filing of this suit. Article IX(B) clearly allows an employer to by-pass the arbitration requirement if the dispute involves a work stoppage. Although parties to a collective bargaining agreement must normally exhaust contractual arbitration before pursuing other remedies,
see Mautz & Oren,
Local 150 also argues that despite the no-strike clause, it still had a right to sympathy strike
5
because the National Agreement did not specifically prohibit it. Relying on our decision in
Indianapolis Power and Light v. NLRB,
However, whether we apply the rule stated in Indianapolis Power or not, 6 the language of the National Agreement, as well as certain extrinsic evidence, convince us that the parties intended the kind of strike at issue to be included in the no strike clause. First, the no-strike clause is accompanied by a specific sympathy strike exception which does not cover Local 150’s actions at Herscher. That exception provides:
It shall not be a violation of this Agreement or of the no-strike clause if members of the International Union of Operating Engineers refuse to cross a picket line established by another craft union within the pipe line industry.
Article IX(D). This exception for certain sympathy strikes — those in observance of other unions’ picket lines — strongly implies that sympathy strikes in general were included "in the no-strike clause, for if they were not, there would be no need for an exception. The fact that sympathy strikes in favor of Local 150’s own picket lines are not included in the specific exception similarly indicates that the union’s actions here fell “within the purview of the no-strike clause.”
Indianapolis Power,
Damages and Interest
Local 150 next argues that even if it engaged in improper secondary activity at Herscher, the court erred in awarding Coolsaet damages, or alternatively, that its damage award was excessive. In either case, claims Local 150, the court erred in awarding pre-judgment interest.
Damages
The trial court awarded Coolsaet damages based on what the court found to be a twelve day delay (in addition to the eleven days of the strike itself) in completion of the project which was directly attributable to the strike. 7 This post-strike delay resulted from work that had to be redone and lost time and efficiencies remobilizing the project. The damages figure includes increased payroll and equipment expenses as well as other miscellaneous expenses associated with the strike-induced delay.
Local 150 now claims that the award should be reversed because the damages calculation was purely speculative.
See Mid-America Tablewares v. Mogi Trading Co.,
Next, relying on a decision from the Ninth Circuit,
Matson Plastering Company, Inc. v. Plasterers & Shophands Local 66,
the union claims that the court erred in awarding damages based on equipment expenses because only “out of pocket expenses paid to third parties as a result of picketing” are compensable under Section 303.
Interest
After requesting additional briefing, the trial court decided to award Coolsaet an additional $105,221, which represents the compounded interest on Coolsaet’s total damage award except for the amount awarded for equipment costs.
Beelman Truck Company v. Chauffeurs, Teamsters, Warehousemen and Helpers,
Initially, Local 150 argues that Cool-saet’s request for interest, which is normally treated as a Rule 59(e) motion, was untimely because it was filed more than
*661
ten days after the court entered its judgment. Fed.R.Civ.P. 59(e); see
McNabola v. Chicago Transit Authority,
Next, the union claims that because their actions were not intentional or outrageous and because the underlying damages were speculative, prejudgment interest was inappropriate.
See Gorenstein Enterprises v. Quality Care-USA
Cross-Claim for Interest
Before calculating the amount of prejudgment interest, the district court subtracted from the total damages amount the sum designated as Coolsaet’s equipment expenses. Apparently, the trial court concluded that because Coolsaet owned its equipment this money was not “out-of-pocket” and could not have been invested, so it would not have earned any interest. Coolsaet maintains, however, that this decision deprived it of complete compensation and the interest award should be increased. We agree. Prejudgment interest is based on the notion that a plaintiff is not fully compensated unless it receives interest for the time it was deprived the use of its money.
See Partington v. Broyhill Furn. Indus. Inc.,
Money today is not a full substitute for the same sum that should have been paid years ago. Prejudgment interest therefore is an ordinary part of any award under federal law. By committing a tort, the wrongdoer creates an involuntary creditor. It may take time for the victim to obtain an enforceable judgment, but once there is a judgment the obligation is dated as of the time of the injury.... Prejudgment interest at the market rate puts both parties in the position they would have occupied had compensation been paid promptly.
In re Oil Spill by Amoco Cadiz,
Rule 38 Sanctions
After briefs were submitted on this appeal, Coolsaet moved for damages and costs pursuant to Rule 38 of the Federal Rules of Appellate Procedure. Rule 38 states: “If a court of appeals shall determine that an appeal is frivolous, it may award just damages and single or double costs to the appellee.” In
Spiegel v. Continental Illinois Bank,
Conclusion
We agree with the district court’s decision that Local 150 engaged in illegal secondary activity and breached the no-strike clause in the collective bargaining agreement it had with Coolsaet. We also agree with all but one of the district court’s damages determinations. Therefore, we AffiRM in part, Reverse in part and RemaNd for recalculation of prejudgment interest.
Notes
. The following account is based on the district court’s finding of facts pursuant to Fed. R.Clv.P. 52(a).
. Although the court did not hold that
Moore Dry Dock
applied to this case, it nonetheless concluded that under its standards Local 150’s conduct was not legal. While we share the court's skepticism that the Herscher facility is a single work site triggering
Moore Dry Dock,
because the court found actual evidence of an intent to exert secondary pressure we need not decide this question.
See Mautz & Oren, Inc. v. Teamsters, Chauffeurs, and Helpers Union, Local No. 219,
. Article IX(A) provides:
All grievances, disputes, differences of opinion and other questions concerning this Agreement shall be settled in accordance with the procedures for settlement of grievances and disputes set out in [Article X, the arbitration clause] below.
. Section 301 of the LMRA confers federal jurisdiction over claims for breach of collective bargaining agreements. See 29 U.S.C. § 185.
. As the term is used in this case, a sympathy strike is essentially the refusal of union members to cross a picket line when they are not themselves the subject of the dispute.
See Gary Hobart Water Corp. v. NLRB,
. We recognize that the rule stated in
Indianapolis Power
is not necessarily the law of this circuit. Our decision in that case was the result of its unusual procedural posture. The Court of Appeals for the D.C. Circuit had announced the rule (that in the absence of extrinsic evidence, no strike clauses do not automatically include sympathy strikes) prior to remanding the case.
Indianapolis Power,
. The court essentially arrived at the twelve day figure by comparing — with certain adjustments — the pre-strike estimated completion or "tie-in” date with the actual "tie-in” date.
. Local 150 also argues that the court failed to deduct the damage to Coolsaet attributable to lawful primary conduct from unlawful secondary activity.
See Boxhorn’s Big Muskego Gun Club, Inc. v. Electrical Workers Local 494,
. Contractors must charge themselves rent on equipment they own. This rent essentially accounts for the depreciation (the real decline in the value of the equipment) as well as finance costs, insurance and certain taxes. As the equipment sits idle, these expenses accumulate without generating any offsetting revenue. Even if the equipment is owned by the contractor free and clear of finance charges, keeping the equipment on a project longer than expected without a corresponding increase in revenue entails opportunity costs.
See Frito-Lay, Inc.,
. Our conclusion might have been different if, for example, the court had concluded that the equipment expenses were far more speculative than the other expenses or were otherwise suspect.
