OPINION OF THE COURT
This is аn appeal from a final order of the United States District Court for the Western District of Pennsylvania vacating an arbitration award as a violation of public policy. The district court’s decision,
*147 I.
The arbitration award under reviеw was rendered under a collective-bargaining agreement (“the Agreement”) between the United States Postal Service (“the Postal Service”), an independent federal agency, and the National Association of Letter Carriers, AFL-CIO (“NALC”), the labor organization which represents the nationwide bargaining unit of all postal employеes. Article 15 of the Agreement provides a multi-step grievance procedure culminating in binding arbitration before a neutral arbitrator selected from an established panel of postal service employees. The grievant is a postal employee, Edward Jackson. The Postal Service suspended and discharged Mr. Jаckson pursuant to Article 16 of the Agreement which sets forth a “just cause” standard for discharge, and subjects all forms of discipline to the grievance-arbitration procedure in Article 15.
In July 1986, an arbitration hearing was held before arbitrator William J. LeWinter. The arbitrator found that the Postal Service had taken disciplinary action against Mr. Jаckson because, while off-duty, he had fired gun shots at his Postmaster’s empty parked car, damaging the windshield, dashboard and front seat — an incident to which Mr. Jackson voluntarily confessed. In evaluating whether the forms of disciplinary action taken against Mr. Jackson violated Article 16 of the agreement, arbitrator LeWinter concluded that, аlthough Mr. Jackson’s “serious act” warranted some disciplinary action, other facts indicated that the Article 16 “just cause” standard for discharge was not met. In particular, arbitrator LeWinter found that the Postal Service management had failed to take into account the following mitigating circumstances that ought properly to hаve been considered — specifically:
During his thirteen years of work prior to the offense, Mr. Jackson demonstrated a pacific, nonviolent and law-abiding character;
Mr. Jackson had been repeatedly frustrated in his efforts to gain a promotion notwithstanding his consistently good work record and the fact that he was the sole office employee to receive an “excellent” rating on a Postal Service examination designed to identify candidates for promotion;
Mr. Jackson filed a complaint with the Equal Employment Opportunity Commission (“EEOC”) on this basis alleging that he was being discriminated against because he was black;
Mr. Jackson voluntarily withdrew his EEOC cоmplaint as part of an agreement, arrived at in a meeting among him, his EEOC counselor, and the Postmaster, that he would be afforded the opportunity to advance to the “204-B” job category, and to have regular discussions with the Postmaster regarding application for promotions to other specific job categories, on condition of improvement in his work performance;
On the morning before the offense occurred, another meeting was held among Jackson, his EEOC counselor, and the Postmaster to discuss the fact that, after over a year, Jackson had still not been promoted to any of the job categories mentioned in the agreement, during which the Postmaster stated that, due to budget constraints and Jackson’s attitude, Jackson would not be promoted.
Arbitrator LeWinter concluded from these findings of fact that the “supercharged emotional atmosphere,” created by these background events, was responsible for Mr. Jackson’s violent outburst. Weighing the single offense agаinst Jackson’s “13 year deposit in the ‘bank of good will’,” arbitrator LeWinter determined that Article 16, under which penalties are intended not to be punitive and discharge must be for “just cause,” required a lesser penalty than discharge. Accordingly, he directed that Jackson be reinstated. The arbitrator further ruled that Jackson’s suspension without pay violated section 7 of Article 16, which authorizes suspension only if employment may result in damage or injury, because the Postal Service’s decision to suspend was made eleven days after the offense, during which time Mr. Jackson had demonstrated no propensity to violence. On this basis, arbitrator LeWinter awarded Mr. Jackson backpay from the *148 effective date of his suspension to the date of his removal.
Following the issuance of the arbitration award, the Postal Service refused to reinstate Mr. Jackson, and filed this action to vacate the award in the district court.
II.
The district court based its decision to grant the Postal Service’s motion for summary judgment on its aсtion to vacate the arbitration award on the “public policy” exception to the court’s usual deference to the judgment of arbitrators pursuant to collective-bargaining agreements. The district court relied primarily on the articulation of the public policy exception in
W.R. Grace & Co. v. Local Union 759,
In three steps, the district court reasoned that arbitrator LeWinter’s award contravened public policy. First, the district court asserted that “there is an indisputable public policy against permitting an employee to direct physical violence at a superior, and an equally compelling policy against forcing that superior to again employ the man.”

After the district court issued its decision, the Supreme Court handed down
United Paperworkers International Union, AFL-CIO v. Misco,
— U.S. —,
Like the case before us,
Misco
involved the review of an arbitration award, rendered under a collective-bargaining agreement, upholding an employee’s grievance against being discharged for lack of “just cause,” and awarding reinstatement and back pay. The employee in
Misco,
a machine operator, was discharged by his company for violating the company rule against having drugs on the plant premises.

Similarly, the district court in the instant case questioned the arbitrator’s consideration of the evidence in interpreting the just cause provision of the Agreement. However, as the Supreme Court reiterated in
Misco,
in collective-bargaining agreements it is the arbitrator’s judgment “and all that it connotes that was bargained for.”

Applying the
Misco
standard of review to the district court decision, we conclude that the district court exceeded the scope of its reviewing authority. Even assuming, arguendo, that there is a public policy against permitting an employee to direct physical violence agаinst a superior, the district court erred in setting aside the arbitrator’s order of reinstatement. A judgment about the offending employee’s “amenability to discipline” comes under the scope of the arbitrator’s factfinding authority,

The rest of the district court's argument is based on the assumption that the asserted public policy dоes require Jackson's discharge for its fulfillment. Thus, the district court inferred that arbitrator LeWinter must have misconstrued "just cause" and ignored facts from the proposition that just cause for discharge would never obtain if not in this case. That inference, however, depends on the faulty assumption that Jackson's discharge was required in this case. Wе have concluded that Jackson's discharge was not required by law or public policy, and, therefore, we are not warranted in rejecting LeWinter's application of the just cause standard on public policy grounds.
Iv.
Both parties have urged us to reach the question of how narrow the limits of the scope of review of a collective-bargaining arbitration decision are. Thus, NALC urges us to hold, as a basis for reversal, that courts have authority to refuse to enforce an arbitration award only when enforcement would violate positive law or require unlawful conduct. Conversely, the Postal Service argues that a court's reviewing authority under the public policy exception to the enforcement of contracts is broader than that. We do not, however, need to reach this question of where lies the precise boundary around our reviewing authority because, under Misco, the district court has clearly exceeded it.
V.
As an alternative ground for upholding the district court decision, the Postal Service has urged us to consider, as a basis for enlarging our reviewing authority, the fact that it is a public employer, unlike the private employer involved in Misco. We see no basis for distinguishing between the postal service and the private sector with regard to the scope of judicial review of arbitration сonducted under collective-bargaining agreements. The intent of the Postal Reorganization Act, 39 U.S.C. §~ 101-5605, was to extend to the postal service the general labor relations framework of collective-bargaining and binding arbitration established under the National Labor Relations Act, 29 U.S.C. §~ 151-169. Therefore, the framework of grievance рrocedures established under the postal service collective-bargaining agreement is subject to the same general federal policies that counsel against a broad scope of judicial review of collective-bargaining arrangements in the private sector. As the Supreme Court stated, there is "a deсided preference for private settlement of labor disputes without the intervention of government .. ." Misco at ,
