Weber Aircraft, Inc. (“Weber”) brought this action against General Warehousemen and Helpers Union Local 767 (“the Union”), seeking to vacate an arbitration award in favor of the Union. The district court rendered summary judgment in favor of Weber, vacating the arbitration award. The Union appealed. We reverse the judgment of the district court and reinstate the arbitration award.
I.
A.
Weber and the Union entered into a collective bargaining agreement (“CBA”) with arbitration provisions. The CBA reserves to Weber “the right to ... suspend, and/or discharge for just cause.” “Just cause” is not defined in the CBA, though the company rules and regulations are incorporated into the CBA and violations of the rules “could be sufficient grounds for disciplinary action, ranging from reprimand to immediate discharge depending on the severity.” “Category 1” violations are subject to “Immediate Suspension for investigation/Possible Discharge.” Sexual harassment is a Category 1 violation. A decision to suspend or discharge an employee is subject to the grievance and arbitration provisions of the CBA. Under those provisions, to find in favor of Weber’s suspension or discharge of an employee, the arbitrator has to find that Weber had just cause for the particular disciplinary action taken.
Roy Sewell had been employed by Weber as a lead-man for more than twenty-five years and was covered by the CBA. In April 1998, Sewell was accused of sexually harassing a female co-worker, and was suspended pending an investigation of the accusation. During Weber’s investigation, two additional female co-workers accused Sewell of sexually harassing them. Based on its investigation, Weber discharged Se-well in May 1998. The Union filed a grievance seeking Sewell’s reinstatement with backpay, and the matter was presented to an arbitrator to determine whether Sewell was “discharged for just cause.” The arbitrator found that Sewell engaged in conduct constituting Category 1 sexual harassment. However, the arbitrator found that “the discipline granted [Sewell] was excessive, given the facts of the case and [Sewell’s] prior record of service.” 1 The arbitrator found that Weber did not have just cause to discharge Sewell and ordered that he be reinstated without backpay for the eleven-month period between his discharge and the arbitrator’s award, effectively commuting Sewell’s discipline to an eleven-month suspension without pay. Weber filed suit in district court and successfully moved for summary judgment vacating the arbitration award. The Union appealed.
The district court’s assigned reasons for rendering summary judgment in favor of Weber were that (1) the arbitration award exceeded the scope of the arbitrator’s authority under the CBA, and (2) the reinstatement of Sewell (although without backpay), despite finding that he had sexually harassed female employees, was contrary to the public policy against sexual harassment in the workplace. Because we conclude that the arbitration award is con *824 gruous with the CBA and public policy, we must reverse.
B.
In an appeal from a grant of summary judgment in a suit to vacate an arbitration award, we review the district court’s ruling de novo.
Six Flags Over Texas, Inc. v. Int’l Bhd. of Elec. Workers Local No. 116,
C.
In the present case, the arbitrator did not act beyond the ambit of his authority under the CBA by determining that, while there was not just cause to fire Sewell, there was just cause to suspend him without backpay for some eleven months. The CBA provides that a Category 1 violation justifies “Immediate Suspension for Investigation/Possible Discharge.” The arbitrator interpreted the CBA as authorizing a range of punishment for Category 1 violations; discharge being the appropriate sanction for the more serious violations, and suspension the suitable penalty for less aggravated infractions. This interpretation is plausible because the CBA provides that a Category 1 violation calls for suspension and possible, not certain, discharge; and because the CBA does not establish a fixed definition of “just cause,” plainly indicating that the standard varies with the level of punishment. Thus, the arbitrator’s determination that a particular Category 1 violation may be sanctioned by a suspension without pay arguably “draw[s] its essence from the contract and [does not] simply reflect the arbitrator’s own notions of industrial justice.”
Misco,
Weber argues that this circuit’s decision in
E.I. DuPont de Nemours & Company v. Local 900 of the International Chemical Workers Union,
In
DuPont,
this court affirmed the district court’s vacating of an arbitration award that reinstated two employees because the CBA in that case did not permit the arbitrator to construe or apply the contract to authorize a sanction other than discharge.
Id.
at 459. The effect of the characterization of the employees’ conduct as “[unquestionably, ... a discharge offense” under that CBA was emphasized by
*825
the opinion’s heavy reliance on the reasoning in
Delta Queen Steamboat Co. v. District 2 Marine Engineers Beneficial Association. Id.
at 458-59 (citing
Delta Queen,
Neither
DuPont
nor
Delta Queen
is determinative of our decision in the present case. The restrictive CBA provisions in those cases, viz., the strict definition of “proper cause” in
Delta Queen,
and the exclusion of a lesser sanction than discharge in
DuPont,
prevented the arbitrators from adopting arguable constructions or applications more favorable to the employees. Of course, we are not empowered to reverse the arbitrator’s award simply because the arbitrator’s arguable construction or application of the CBA may deviate from that which this court, if authorized, would adopt as its own construction of the CBA; or because of superficial differences in results between the court cases. So long as the arbitrator arguably construed or applied the CBA at issue and acted within the scope of his authority thereunder, we must affirm.

Next, we turn to the question of whether the arbitration award was against public policy. Well-established federal labor law favors the protection of an arbitration scheme of “private settlement of labor disputes without the intervention of government.”
Misco,
The Supreme Court, in
Eastern Associated Coal Corp. v. Mine Workers,
“agree[d], in principle, that courts’ authority to invoke the public policy exception is not limited solely to instances where the arbitration award itself violates positive law.”
Applying the foregoing precepts, we, like the Supreme Court in
Eastern Associated Coal Corp.,
“cannot find in the [laws], the regulations, or any other law or legal precedent an ‘explicit,’ ‘well defined,’ ‘dominant’ public policy to which the arbitrator’s decision ‘runs contrary.’ ”
Id.

Misco,
Conclusion
Accordingly, the judgment of the district court is REVERSED, and the arbitrator’s award is REINSTATED.
Notes
. The facts that the arbitrator found to mitigate Sewell's sexual harassment conduct were that (1) two alleged incidents occurred prior to the inclusion of sexual harassment as a Category 1 offense and were never reported to the Company prior to its investigation; (2) evidence was insufficient to prove that the harassment resulted in the victim being "truly threatened by [Sewell’s] actions, to the point that [Sewell] should be permanently removed from the workplace”; and (3) Sewell "ha[d] a record of long standing and valuable service to the Company and his only prior discipline was reversed in arbitration.”
. In his concurring opinion, Justice Scalia characterized this “narrow” exception as "a giant ‘Do Not Enter’ sign.”
Eastern Assoc. Coal Corp.,
. Our conclusion is in accord with the decisions of the other Circuits that have addressed the issue of whether there is a clear public policy against reinstating sexual harassers.
See Westvaco Corp. v. United Paperworkers Int'l Union,
In
Westvaco Corp. v. United Paperworkers International Union,
the Fourth Circuit noted that “while it is certainly true that there is a public policy against sexual harassment, ... [t]here is no public policy that every harasser must be fired. Instead, a company must 'exercise[] reasonable care to prevent and correct promptly any sexually harassing behavior.’ ”
Contrary to Weber's argument, the Second and Third circuits have not squarely addressed the issue. In
Newsday, Inc. v. Long Island Typographical Union,
