This case requires us to answer two questions of first impression in any United States Court of Appeals: whether an employee suing an employer under the Railway Labor Act for discharging him because of his union-organizing activities is entitled (1) to a jury trial and (2) to seek punitive damages. We hold that he is entitled to both, and we reverse and remand for further proceedings.
In June 1991, American Trans Air (ATA) fired Mark Lebow from his position as an airline pilot. Lebow filed suit under the Railway Labor Act (RLA), 45 U.S.C. § 151 et seq., claiming that ATA discharged him because of his union-organizing activities. 1 He sought reinstatement, back pay, benefits, compensatory damages, and punitive damages. Lebow also demanded a jury trial. ATA claimed that it terminated Lebow because of his job performance. In addition, the airline argued that the RLA does not provide Lebow with the right to a jury trial *664 or to recover punitive damages. The district court held that Lebow could seek punitive damages but was not entitled to a jury trial. After a bench trial, the district court entered judgment in favor of ATA. Lebow appeals, arguing that he was denied his Seventh Amendment right to a trial by jury.
I.
As an initial matter, ATA argues that we need not reach the question of whether Lebow was entitled to a jury trial because the evidence introduced at trial was insufficient to support his claim of anti-union animus. ATA would be entitled to judgment as a matter of law only if “ ‘there can be but one conclusion from the evidence’ and inferences reasonably drawn therefrom.”
Bronk v. Ineichen,
Lebow joined ATA as a Flight Engineer (the third in command on an airplane) in 1983. He was promoted to First Officer in 1985 and to Captain in 1989. From 1989 to 1991, he served as the Captain of a Boeing 727 airplane.
During Lebow’s tenure at the airline, ATA’s pilots were not represented by a union. In 1989, Lebow began working on a campaign to have the pilots at ATA represented by the Airline Pilots Association (ALPA). The campaign was quiet, even secretive. Lebow and Earl Rogers, another ATA pilot, testified that the organizers of the ALPA campaign proceeded quietly because, as ATA opposed unionization, they feared retaliation. Rogers identified Lebow as one of the “primary organizers” of the campaign. The drive to bring the ALPA to ATA however, ultimately failed. 2
Lebow testified that he was actively involved in union-organizing activities. He passed out authorization cards and also “spoke with many people, anybody that wished to talk about” the union. He attended meetings in Virginia and Las Vegas to discuss the possibility of organizing ALPA representation at ATA. In addition, he discussed his pro-union sentiments with ATA officials on several occasions. In early 1991, Lebow resigned from the Crew Scheduling Advisory Committee (a committee of pilots and managers composed to discuss scheduling issues). Lebow stated that he told Steve Cooper, ATA’s Vice President of Flight Operations, that “I was no longer going to attend the Crew Scheduling Advisory Committee [meetings] and that I would continue to work on my concerns through the union by trying to organize a union.” Aso in 1991, Lebow attended a training class in Indianapolis where Jim Hlavacek (an Executive Vice President of ATA) and Ken Wolf (another senior manager) showed the pilots a videotape produced by the company to discourage flight attendants from organizing a union. 3 A discussion between Hlavacek and the phots ensued, and Lebow presented the union perspective in response to the management perspective offered by Hlavacek. Following the training class, Lebow and Hlavacek had a private conversation, and Lebow explained to Hlavacek why he believed that a union was necessary. Hlavacek told Cooper about his discussion with Lebow.
Lebow testified that in May or June of 1991, he had a conversation with his direct supervisor, Captain Tom Leonard, during which Leonard asked him, “what do you think about unions?” Lebow responded that he felt the pilots “had no choice but to go to the unions.” Lebow’s wife, Donna Lebow (she was then his fiancee) was present during this conversation, and she confirmed Lebow’s account of the exchange. Cooper and Hlavacek acknowledged that they knew of Lebow’s pro-union sentiments, but they denied knowledge of his union-organizing activities.
ATA made no secret of its opposition to unionization. Cooper felt that unionization would have an adverse financial impact on ATA and Hlavacek opposed unions because he had previously worked at Continental Air *665 lines, where he observed a union “basically tearing the company apart.” Cooper wrote several letters to the pilots in an effort to discourage them from bringing either the ALPA or the Teamsters to ATA. In addition, ATA managers wore “One Team” badges in opposition to unionization efforts.
Rogers testified that Mike Carlozzi, ATA’s Chief Pilot, told him that “a union would never work at ATA that it would interfere with the [airline’s] competitive position within the industry.” Rogers stated further that Carlozzi “followed up his remarks by talking about what a difficult time it was in the industry for pilots to find work, and on his desk he had a large stack of resumes.” Finally, Rogers testified that two pilots (Rick Reese and Andy Sperling), whom he knew to be active union organizers, were fired by ATA
In June 1991, Lebow was scheduled for a proficiency check, which as a Captain he was required to take twice a year. Lebow was originally scheduled to take the “check ride” on June 18, but ATA rescheduled his check for June 10 and assigned a different “cheek airman” to administer the check, Captain Stonehouse. Lebow stated that at a lunch meeting prior to the check, Stonehouse commented that “he hoped that all flight attendants that voted for the union would either lose their jobs or have serious pay cuts.” Stonehouse then administered the proficiency cheek to Lebow. The check lasted 40-45 minutes rather than the usual two hours. Lebow failed the check, and it was the first time that he had failed a proficiency check (he had taken approximately 15 previous checks) during his employment with ATA.
After failing the check, Lebow discussed the matter with Cooper. Cooper told him to be prepared to take another proficiency check. In addition, Cooper observed that “we [Cooper and Lebow] have had our differences.” Cooper then pounded on the table and said, “this will not continue.”
After this meeting, Lebow discussed his failure on the proficiency check' with Rich Moreau, ATA’s Chicago base manager. Le-bow testified that Moreau told him that “he was going to ... try to help me out ... [but] the wheels were already turning and he didn’t think he could do very much.” Lebow claimed that Moreau told him that “this did not have to do with my performance but, instead, had to do with my conversation with Mr. Hlavacek and also because of [union] organizing.”
On June 24, 1991, Lebow and Cooper met again, ostensibly to discuss the failed proficiency check. Leonard and Carlozzi were also present at the meeting. Cooper opened the meeting by informing Lebow that he was fired. Lebow asked Cooper what the reason was, and Cooper replied, “technical proficiency.” Carlozzi then added “not conforming to company policy,” but Cooper “quickly corrected [him] back to technical proficiency.”
At trial, ATA argued that it fired Lebow because of the combined effect of the failed proficiency cheek and three other incidents in his work history: (1) a failed attempt to “upgrade” to Captain in May 1988 (when Lebow was still a First Officer); (2) an incident in St. Thomas, Virgin Islands in April 1990 where the wing tip of Lebow’s plane may have touched the runway during takeoff; and (3) an aborted take-off in Phoenix in May 1990. 4 ATA presented evidence (including expert testimony) that Lebow made mistakes during these incidents that justified his discharge. Lebow presented evidence (including expert testimony) that (1) the proficiency check was administered unfairly; (2) Lebow performed proficiently during the St. Thomas and Phoenix incidents; and (3) the failed attempt to upgrade was caused by emotional distress that Lebow was experiencing (the night before the upgrade attempt, Lebow’s wife informed him that she wanted a divorce). Additionally, Lebow contended that ATA should not have held his failure on the initial attempt against him because he successfully upgraded to Captain in 1989.
Athough we have not previously addressed this issue, we believe that the same burden-shifting method employed in unlawful discharge claims brought under the
*666
National Labor Relations Act (NLRA) applies to claims brought under the RLA.
See ALPA v. Eastern Air Lines, Inc.,
To establish that anti-union animus was a substantial or motivating factor in his discharge, an employee must demonstrate that (1) he “engaged in union ... activities; (2) the employer knew of the employee’s involvement in protected activities; (3) the employer harbored animus towards those activities; and (4) there was a causal connection between the employer’s animus and its discharge decision.”
Carry Companies of Illinois, Inc. v. NLRB,
Although there is no dispute that Lebow engaged in union activities, ATA contests the sufficiency of Lebow’s proof on the remaining three elements. We conclude, however, that Lebow presented sufficient evidence for a rational jury to find in his favor.
First, Lebow’s many discussions, debates, and exchanges with the ATA management concerning unionization, Rogers’ testimony that Lebow was one of the “primary organizers” of the ALPA campaign, and Lebow’s testimony that he engaged in a number of union-organizing activities (including attending out-of-town planning sessions and handing out authorization cards) constitute sufficient circumstantial evidence for a jury to infer that ATA’s management knew of Lebow’s union involvement. The district court credited Cooper’s statement that he did not know of Lebow’s activities, and the finder of fact of course has the duty of judging the credibility of witnesses. But a reasonable factfinder could have arrived at a different conclusion.
In addition, Lebow presented sufficient evidence for a jury to infer that ATA harbored anti-union animus. The trial transcript reveals that ATA’s management strongly opposed unionization. ATA argues that mere opposition to unionization is not synonymous with anti-union animus. We have stated that under the NLRA, “noncoercive expressions of opinion are not to be used as evidence of an unfair labor practice.”
Carry Companies,
Next, the finder of fact could reasonably infer a causal connection between Lebow’s discharge and his union activities. The numerous exchanges between Lebow and ATA’s management concerning unionization occurred during the spring of 1991, and the debates continued until his discharge in June 1991. In addition, Moreau’s statement implies that ATA’s decision was related to Le-bow’s union-organizing activity. Finally, Cooper’s statement that his differences with Lebow “will not continue” and Carlozzi’s statement that Lebow’s discharge was for “not conforming to company policy” may imply a causal connection. This evidence is sufficient to allow a reasonable factfinder to conclude that Lebow’s discharge was related to his union activities,
Finally, both sides presented voluminous expert testimony concerning the incidents that ATA claimed were the real reasons for Lebow’s discharge and that Lebow claimed were mere pretexts. The resolution 0f tbjs “battle of experts” is best reserved for ^be Lier of fact. Thus, because a rational factfinder could find in favor of Lebow, we must determine whether he was entitled to a jury trial.
II.
Lebow argues that the district court infringed his Seventh Amendment rights by denying him a jury trial. No circuit has discussed whether an employee suing his employer under the RLA for discharging him because of his union activities is entitled to a jury trial. 8 We conclude that Lebow has a Seventh Amendment right to present his claim to a jury.
The Seventh Amendment states that “[i]n suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved.” By using the phrase “suits at common law,” the Constitution mandates jury trials for legal actions but not for equitable actions.
Chauffeurs, Teamsters and Helpers, Local No. 391 v. Terry,
*668
The federal courts have long since abolished the distinction between “courts of law” and “courts of equity;” therefore the Supreme Court has adopted a two-part test to determine whether a claim qualifies as legal or equitable. First, we must “compare the ... action to 18th-century actions brought in the courts of England prior to the merger of the courts of law and equity. Second, we examine the remedy sought and determine whether it is legal or equitable in nature. The second inquiry is the more important in our analysis.”
Terry,
A.
We can identify no exact eighteenth-century parallel for Lebow’s claim that ATA fired him because he was engaged in union-organizing activities. In eighteenth-century England, labor unions were illegal, and employees who engaged in collective bargaining were subject to criminal penalties.
See Terry,
Despite the lack of a precise eighteenth-century counterpart, Lebow’s unlawful discharge claim, in our view, may be appropriately analogized to a common-law breach of contract action. In
Terry,
the Supreme Court concluded that although an employee’s suit against a union for breach of duty of fair representation had no true eighteenth-century analogue, it was, at least in part, similar to a common-law breach of contract action.
Terry,
In addition, unlike nineteenth-century American law, under which employees served at the will of their employers, the common law presumed that a contract existed between employers and employees.

Due Process and Separation of Powers: The Effort to Make the Due Process Clause Nonjusticiable,
60 Tex.L.Rev. 875, 897 n. 91 (May 1982). Under British common law, if there was no contract specifying a term of employment, “the law construe[d] it to be a hiring for a year.” 1 W. Blackstone,
Commentaries on the Laws of England
425. Employment by contract was the rule in eighteenth-century England, so an improper discharge would have been viewed as a breach of contract. Thus, Lebow’s unlawful discharge claim is comparable to a common-law action for breach of an employment contract.
See Waldrop v. Southern Co. Services, Inc.,
Lebow’s lawsuit is also similar to a common-law tort action. In
Curtis v. Loether,
Hence, Lebow’s unlawful discharge suit is comparable to common-law contract and tort actions. In eighteenth-century England, breach of contract actions were generally tried at common law,
see
E. Allen Famsworth,
Contracts, Second Edition §§ 1.5,11.2
(Little, Brown 1990), and the
Terry
court described a common-law breach of contract claim as a “legal issue.”
Terry,
B.
The second and most critical factor in the
Terry
analysis is the nature of the remedies that a plaintiff wishes to obtain. “The Seventh Amendment ... requires a jury trial upon demand[ ] if the statute creates legal rights and remedies, enforceable in an action for damages in the ordinary courts of law.”
Curtis, 415
U.S. at 194,
Lebow requested punitive damages in addition to reinstatement and back pay.
11
The district court held that he was entitled to seek punitive damages but could not have a trial by jury. We cannot agree that Lebow could have a right to request punitive damages but not to demand a jury trial. Punitive damages have traditionally been viewed as a legal remedy that must be imposed by a jury.

Tull v. United States,
In holding that Lebow’s request for punitive damages did not entitle him to a trial by jury, the district court relied on
Lynch v. Pan American World Airways, Inc.,
In
Franklin v. Gwinnett County Public Schools,
1.
First, ATA contends that Congress has indicated that punitive damages are not recoverable under the RLA. The text of the RLA is silent concerning what remedies are available when an employee sues his employer for discharging him because of his union-organizing activities. However, when a suit is brought under an implied right of action, we may also look to Congressional action taken after the cause of action was implied to determine what remedies are available.
See Franklin,
Moreover, in eases such as Lebow’s where a
non-union
employee is suing his employer for wrongful discharge, the criminal sanctions authorized under § 152 may not even be available. Section 152 requires the Department of Justice to initiate a criminal prosecution if the
union
representing the carrier’s employees reports the illegal conduct to the United States Attorney.
13
Section 152, however, does not provide individual employees with the right to petition the United States Attorney to bring a criminal prosecution.
See Belton v. Air Atlanta, Inc.,
ATA also argues that the
Franklin
presumption that all appropriate remedies are available does not apply because the RLA “expressly enumerate[s] the remedies available to plaintiffs.”
Franklin,
2.
Finally, ATA contends that punitive damages are not appropriate in suits under the RLA because they will upset the delicate balance of power between employers and employees. The over-arching goal of the federal labor laws is to achieve industrial peace, improve wages, and improve working conditions “by fostering a system of employee organization and collective bargaining.”
Vaca v. Sipes,
In
Foust,
the Supreme Court held that an employee suing a union under the RLA for breach of the duty of fair representation may not collect punitive damages.
Foust,
An unlawful discharge suit by an unrepresented employee against his employer, however, is quite different from a fair representation suit by a union employee against his union. Awarding punitive damages to non-union employees would not interfere with the collective bargaining process because there is no collective bargaining process with which to interfere. On the contrary, if an employer discharges an employee for attempting to organize a union, it is the employer that is interfering by chilling union activity. An employee in such a situation cannot appeal to a union for help; his recourse is to file an individual suit, as Lebow did. It is possible that if the only sanctions available are remedies such as reinstatement and back pay, employers may not be sufficiently deterred from inappropriately discharging union organizers.
See Kemezy v. Peters,
III.
In sum, Lebow’s claim is similar to common-law tort and contract actions, and he has the right to seek punitive damages, which the Supreme Court has characterized as a legal remedy. Thus, Lebow raises a legal claim, and the Seventh Amendment guarantees his right to a trial by jury. In addition, because ATA would not have been entitled to judgment as a matter of law, the district court’s error in denying him a jury trial was not harmless. Accordingly, we must remand the case for a jury trial. To the extent that Lebow seeks both legal and equitable relief, the jury shall impose any legal relief, while the judge shall impose any equitable relief.

. At oral argument, ATA attempted to discredit this statement because Moreau did not testify; rather, Lebow testified that Moreau made the statement. This fact, however, is irrelevant because the statement was properly introduced into evidence as an admission. Fed.R.Evid. 801(d)(2). ATA could have called Moreau to rebut this testimony, and in any event the trier of fact is entitled to judge Lebow’s credibility as a witness.
. The district courts that have addressed the issue are split. In
Freiburger v. Emery Air Charter, Inc.,
. In the early nineteenth century, American law was more tolerant of organized labor than British law. See William E. Forbath, The Shaping of the American Labor Movement, 102 Harv.L.Rev. 1109, 1149 n. 170 (April 1989). Prior to the civil war, there were no reported cases of American courts punishing labor organizers for noncoercive practices, and those who were prosecuted received light sentences. Id. In the late nineteenth and early twentieth centuries, however, the federal courts frequently used their injunctive powers to restrain labor strikes, (usually railway strikes). See id. at 1155-65.
. Plaintiffs in eighteenth-century contract actions would, however, occasionally seek relief in chancery (equity) courts. Farnsworth,
Contracts
§ 11.2. In addition, the
Smith
court noted that common-law tort and contract suits "could have been brought either in courts of law or courts of equity, depending on the relief sought.”
Smith,
. Lebow asserts that he also sought compensatory damages, and his complaint does contain a request for compensatory damages. The complaint, however, does not allege that Lebow suffered any harm other than the loss of his job. Lebow does not, for instance, claim to have suffered emotional distress or other harms that should be compensated with money damages. Accordingly, the only monetary damages that he specifically requests are back pay, benefits, and punitive damages. Lebow’s vague request for compensatory damages is not supported by any facts alleged in the complaint, and thus it is not sufficient to constitute a claim for legal relief. See
Lynch v. Pan American World Airways, Inc.,
. The statute allowed courts to impose civil fines of up to $10,000 per day for violations of the Act.

. Section 152 (Tenth) states in relevant part:
It shall be the duty of any United States Attorney to whom any duly designated representative of a carrier’s employees may apply to institute in the proper court and to prosecute under the direction of the Attorney General of the United States, all necessary proceedings for the enforcement of the provisions of this section, and for the punishment of all violations thereof. 45 U.S.C. § 152 (Tenth) (emphasis added). The RLA defines "representative” as "any person or persons, labor union, organization, or corporation designated either by a carrier or group of carriers or by its or their employees, to act for it or them.” 45 U.S.C. § 151. Accordingly, the “duly designated representative of a carrier's employees” is any union or.other entity chosen by the employees to represent them.
. In
Maas v. Frontier Airlines, Inc.,
. Because we hold that Lebow has the right to seek one form of legal relief (punitive damages), a jury trial is necessary, and we need not decide whether the other relief sought (reinstatement with back pay and benefits) qualifies as legal or equitable.
