Plaintiff-appellant Glenn Brown filed this action in state court seeking enforcement of an arbitration award in his favor against his employer Witco Corporation. After the case was removed to federal court by Witco, the district court stayed the case and remanded the award to the arbitrator for a specifically limited purpose. Following the arbitrator’s decision on remand, the district court determined that the arbitrator had exceeded the limited authority it had granted him. Accordingly, the district court vacated that part of the arbitrator’s decision that exceeded his authority on remand and enforced the remainder of the award.
Brown and his union, the Paper, Allied-Industrial, Chemical and Energy Workers International Union, Local 4-447 (the intervening plaintiff-appellant) now appeal the district court’s judgment. After threading our way through the twists and turns of the case, and after considering the several arguments made by the parties, we affirm the judgment of the district court.
I
The procedural history of this arbitration case is unusually long and sinuous, and a recitation of that history is necessary to explain the issues raised on appeal.
In 1997, Witco discharged Brown because of chronic absenteeism; however, the company failed to give Brown timely notice of its decision to discharge him, as required by the collective bargaining agreement between Witco and Brown’s Union. In response, the Union filed a formal grievance against Witco on Brown’s behalf, and Witco and the Union ultimately arbitrated their dispute before Arbitrator Raymond L. Britton on January 22, 1999. On May 24, 1999, the arbitrator ordered that Brown “be reinstated with full back pay and seniority and that he be made whole except for overtime.” (The “May 24 Award.”)
Brown was reinstated in accordance with the May 24 Award. However, Witco and the Union were unable to reach an agreement on the calculation of Brown’s back pay award, 1 Consequently, in July and August 1999, Witco and the Union each asked Arbitrator Britton to clarify how the parties should calculate Brown’s back pay award. The Union asked the arbitrator to clarify whether the award included regularly scheduled overtime and night shift premium payments. Witco asked the arbitrator to clarify whether the award should be reduced based on Brown’s interim earnings and Brown’s apparent failure to mitigate his damages by seeking new employment. 2 Neither Witco nor the Union — Brown’s exclusive bargaining representative — ever objected to the clarification requests of the other.
On August 27, 1999, the arbitrator responded to the parties’ clarification re
In endeavoring to determine an appropriate reduction to the Grievant’s back-pay award, the Arbitrator is of the view that it would be more in keeping with the Award if the parties use as a guide, the average wage paid to employees possessing the experience, skills and background of the Grievant in the New Orleans area. Further, the Grievant should be afforded a grace period of three (3) months as representative of the time reasonably necessary to obtain comparable employment.

After receiving the arbitrator’s August 27 Clari
In November 1999, while Witco and the Union were still negotiating the total amount of Brown’s back pay award, Brown personally filed suit against Witco in state court seeking confirmation and enforcement of the original May 24 Award. The Union was not a party to the case at this point. Witco promptly removed the case to federal district court based on federal question jurisdiction and answered Brown’s complaint. 5 Witco then moved to stay Brown’s enforcement action and remand the case to the arbitrator to clarify further how to implement Brown’s back pay award. Brown opposed the remand motion, arguing that the May 24 Award was final and unambiguous in its determination that Brown was entitled to full back pay. The case was referred to a magistrate judge for all proceedings and for judgment in accordance with 28 U.S.C. § 636(c) upon written consent of all parties.
In ruling on the remand motion, the magistrate judge agreed with Witco in large part, holding that the arbitrator retained jurisdiction to clarify his May 24 Award as a matter of law; that the parties had timely requested such clarification; and that the August 27 Clarification Letter is a timely and binding clarification of the May 24 Award. However, the magistrate judge ultimately denied Witco’s motion to remand, finding the clarified arbitration
After the Union intervened, Witco filed a second motion seeking remand to the arbitrator for clarification regarding the proper method for determining the “average wage” figure referenced in the arbitrator’s August 27 Clarification Letter. Brown opposed the motion for the same reasons he opposed Witco’s first motion, but the Union took a different position. The Union agreed that a remand was appropriate, but it argued that the court should remand the case to the arbitrator with instructions to revisit all of his previous determinations regarding Brown’s interim earnings and his duty to mitigate damages.
The magistrate judge agreed with Witco and granted the company’s motion to stay and remand the case. According to the magistrate, it had become apparent that the parties disagreed as to the exact meaning of “the average wage paid to employees possessing the experience, skills, and background of the Grievant in the New Orleans area.” Because such an average wage could not be determined from an undisputed source of information, the magistrate judge concluded that the arbitrator should clarify exactly what that average wage figure should be. However, the magistrate judge found the remainder of the May 24 Award and the August 27 Clarification Letter to be clear and binding on the parties. Accordingly, the magistrate specifically stated that the arbitrator could not reconsider the remainder of the clarified award upon remand. 6
On remand to the arbitrator, Witco presented affidavit evidence from an expert witness regarding the average wage paid to employees in the New Orleans area possessing Brown’s experience, skills, and background. The Union, however, chose not to present any evidence on Brown’s behalf regarding the average wage issue. Instead, the Union presented evidence only to support its claim that Brown had made a reasonable good faith effort to search for employment and mitigate his damages. Over Witeo’s objection, Arbitrator Britton accepted such evidence. On December 14, 2001, the arbitrator found that Witco’s evidence supported a finding of an average wage of $21.51 per hour for an average work week of forty-two hours. (“December 14 Remand Decision.”) However, Arbitrator Britton concluded that
inasmuch as the parties have agreed to the figure of $85,801.58 calculated as back wages, the Arbitrator finds that the Grievant is entitled to the sum of $85,801.58 less the amount paid to the Grievant of $13,441.57 and $3,500 derived from outside work. It is the further view of the arbitrator that the work ethic of the Grievant should be considered as a factor in the computation of the back wages due the Grievant.... Because of this demonstrated poor work ethic, a further deduction of $8,500 is warranted.... So calculated, the total amount due the Grievant is $60,360.01.
December 14 Remand Decision at 2. In other words, the arbitrator essentially abrogated the determinations that he made in the August 27 Clarification Letter, which provided for a “reasonable deduction” in Brown’s back pay award on account of Brown’s failure to satisfy his affirmative duty to mitigate his damages by seeking comparable employment. The arbitrator also ignored the specific formula
After receiving the arbitrator’s clarification decision, the parties jointly moved the magistrate judge to lift his stay on the case, and they filed cross motions for summary judgment. On April 26, 2002, the magistrate judge granted Witco’s motion for summary judgment and denied the summary judgment motions filed by Brown and the Union. (Hereinafter, the “April 26 Summary Judgment Order.”) In doing so, the magistrate judge reaffirmed his prior decision holding Arbitrator Brit-ton’s August 27 Clarification Letter to be a binding clarification of his initial award. The magistrate judge further held that the arbitrator exceeded the scope of his authority under the remand order by revisiting the clarifications he made in his August 27 Clarification Letter to the parties authorizing a “reasonable deduction” in Brown’s back pay award on account of Brown’s failure to establish his good faith effort to seek comparable employment and prescribing a specific method for calculating such a deduction. Because those unambiguous determinations had already been confirmed and enforced by the magistrate judge’s remand order, the magistrate held that Arbitrator Britton had no authority on remand to reconsider them:
The only issue upon remand was “to determine exactly how that ‘average wage’ should be calculated” and, upon determining that number, to plug it into the formula and calculate the amount of back wages due under that formula.
April 26 Summary Judgment Order at 12 (emphasis in original). Accordingly, the magistrate judge vacated those parts of the arbitrator’s remand decision that exceeded the scope of his limited authority on remand. The magistrate judge enforced the remainder of the Arbitrator’s decision and awarded Brown back pay in the amount of $85,801.58 reduced by an amount equal to $21.51 per hour for a forty-two hour week for the period of time beginning three months after the date of Brown’s discharge through the date of his reinstatement.
II
Both Brown and the Union timely appealed the district court’s final judgment. On appeal, Brown argues that the magistrate judge erred by not enforcing the original May 24 Award, which ordered that Brown be reinstated with seniority and “full back pay.” The Union makes a different argument. It contends that the magistrate judge improperly limited the arbitrator’s authority on remand. The Union argues, as it did below, that the magistrate judge should have remanded the case to the arbitrator for clarification of all the arbitrator’s rulings regarding Brown’s duty and apparent failure to mitigate his damages. Both the Union and Brown further argue that the magistrate erred by vacating parts of the arbitrator’s decision on remand and selectively enforcing the remainder.
It is not surprising that Witco maintains that the magistrate judge got the case exactly right. In response to Brown’s argument, Witco contends that the arbitrator had authority to clarify his original May 24 Award and that the August 27 Clarification Letter is a timely clarification of that award that is binding on all the parties. In response to the Union’s argument, Wit-co argues that the magistrate judge did not err in remanding the case to the arbitrator for the limited purpose of clarifying
This court reviews a district court order confirming and enforcing an arbitration award
de novo,
using the same standard as the district court.
National Gypsum Co. v. Oil, Chemical, and Atomic Workers International Union,
A. Brown’s Arguments.
Brown argues (1) that the arbitrator’s original May 24 Award was final and unambiguous, (2) that Witco failed to file a motion seeking modification of the May 24 Award pursuant to the Federal Arbitration Act in a timely manner, and (3) that the arbitrator lacked jurisdiction to modify the May 24 Award via his August 27 Clarification Letter. Brown therefore argues that the May 24 Award should be enforced as a final award without regard to the August 27 Clarification Letter or the subsequent decision on remand and that he should be awarded $85,801.58 — the amount that the parties have stipulated to be Brown’s full back pay calculated on a straight time basis without consideration of mitigation or any other factors.
(1)
Generally speaking, an arbitration award for “full back pay” is not ambiguous on its face simply because it fails to address whether the award is to be offset by a grievant’s interim earnings or a griev-ant’s failure to mitigate his damages by taking reasonable steps to seek interim employment.
See International Chemical Workers Union, Local 683C v. Columbian Chemicals Co.,
Accordingly, this court can consider Brown’s argument only insofar as it may show a plain error that will result in a manifest miscarriage of justice.

Brown urges the court to disregard the August 27 Clarification Letter because Witco never served Brown or the Union with notice of a motion to modify, correct, or vacate the award as required by the Federal Arbitration Act.
See
9 U.S.C. §§ 1-16 (the “FAA”). However, Brown’s reliance on the statute of limitations of the FAA is misplaced. The FAA does not apply to cases reviewing arbitration awards pursuant to a collective bargaining agreement or any other “contracts of employment of ... workers engaged in for
(3)
Brown argues that the May 24 Award was final and that the arbitrator therefore lacked jurisdiction to clarify the award via his August 27 Clarification Letter. 9 Brown makes this argument based solely on the plain language of the collective bargaining agreement, which provides that “[t]he decision of the arbitrator shall be final and binding on both parties.” However, contrary to Brown’s argument, these plain words alone do not mean that the arbitrator has no authority to interpret or construe his arbitration award, and Brown’s reliance on them provides no real foundation for the argument he makes.
As Witco suggests, Brown’s legal conclusion that the arbitrator lacked authority to issue the August 27 Clarification Letter seems to rely on the doctrine of
functus officio
(“a task performed”) — a common law rule that bars an arbitrator from revisiting the merits of an award once the award has been issued.
See Bayne v. Moms,
Although the doctrine of
functus officio
was strictly enforced at common law (often to thwart the effectiveness of arbitration), in the wake of the Supreme Court’s pro-arbitration decision in
Textile
Finally, in the absence of any contractual provision or formal arbitration rule expressly to the contrary, it seems clear that an arbitrator may exercise his power to clarify the terms of an award when he is asked to do so by parties mutually and without any party’s objection within a reasonable period of time.
See Excelsior Foundry,
B. The Union’s Arguments.
The Union does not argue, as Brown does, that the magistrate erred
The magistrate judge rejected the Union’s remand argument. He found the original award and the August 27 Clarification Letter to be ambiguous only with respect to the precise meaning of “the average wage paid to employees possessing the experience, skills and background of the Grievant in the New Orleans area.” After a de novo review of the record in this case we find no error in the magistrate’s reading of the May 24 Award and the August 27 Clarification Letter. 12
Although the Union argues that
this
clarification ruling made Brown’s arbitration award ambiguous and contradictory, there is nothing unclear or obviously inconsistent about the arbitrator’s words in the original award and in the August 27 Clarification Letter. In the letter, pursuant to the parties’ mutual requests, the arbitrator stated (1) that Brown should be reinstated with full back pay; (2) that Brown had a duty to mitigate his damages and that Brown had failed to show that he had taken reasonable steps to look for new employment; (3) that in calculating Brown’s full back pay, the parties should deduct a reasonable amount from the stipulated amount of $85,801.58 on account of that failure to mitigate his damages; (4) that the parties should use the “average wage” of a similarly situated worker over the interim of Brown’s wrongful discharge as a guide for determining what the total deduction should be; and (5) that the par
Thus, on remand from the magistrate judge, all that the arbitrator had to do under the magistrate judge’s clear remand order was determine precisely what the “average wage” figure should be and use that figure in the formula set forth in the August 27 Clarification Letter to calculate the total amount of Brown’s back pay award. The magistrate judge made it clear that the arbitrator could receive whatever evidence was appropriate and necessary to make this clarification, but the magistrate also made it equally clear that the remainder of the May 24 award and the August 27 Clarification Letter were deemed clear and binding on the parties. Nevertheless, the arbitrator went beyond the express scope of the remand order by issuing a clarification that essentially reversed the determinations that he made in the August 27 Clarification Letter.
Notwithstanding the arbitrator’s disregard of the limited scope and purpose of the magistrate’s remand order, Brown and the Union argue that the district court erred by vacating those parts of the arbitrator’s December 14 Remand Decision that exceeded the scope of the court’s remand order. They argue that the arbitrator’s December 14 Remand Decision was supported by the record and consistent with the terms of the collective bargaining agreement and, given the deferential standard of review that applies in actions to confirm and enforce arbitration awards, that the decision therefore must be enforced in its entirety. This argument seems inapposite to the issue we are specifically addressing. Although it is true that the arbitrator draws his authority from the terms of the collective bargaining agreement and has broad discretion to adjudicate those matters that are properly submitted to him pursuant to a collective bargaining agreement, the immediate issue before us is whether the arbitrator has the authority to disregard the express terms of a federal court’s remand order and effectively reverse determinations that the court has already confirmed to be unambiguous and binding on the parties. Clearly, he does not. Once a court of competent jurisdiction has confirmed that an arbitration decision is unambiguous and binding on the parties, the arbitrator becomes
functus officio
with respect to that portion of the arbitration award and lacks authority to reconsider those aspects of his decision that are unambiguous and binding.

Ill
For the foregoing reasons, the judgment of the district court is, in its entirety,
AFFIRMED.
Notes
. Brown was discharged in July 1997 and reinstated in June 1999. According to the parties, Brown’s total back pay for this period amounted to $85,801.58 when calculated on a "straight time" basis — i.e., when calculated based solely on the company's "straight time” hourly rate without regard to any additional factors, such as regularly scheduled overtime or special premiums paid to workers on the night shift and without regard to any of Brown’s interim earnings.
. Brown testified at the arbitration hearing that he had not been regularly employed from July 1997 until June 1999 and that he earned about $3,000 during this time from self-employment. The Union also submitted Brown’s past earnings statement, dated July 11, 1999, indicating that Brown had earned approximately $2,500 to $3,000 from July 1997 to June 1999 performing odd jobs. There is apparently no testimony as to whether Brown made any effort to find new employment during this time.
. Brown and the Union appear to argue that these determinations were legally erroneous and factually baseless because Witco did not raise mitigation as an affirmative defense during the initial arbitration hearing. However, the Union has not sought to modify or correct the arbitration award. In any event, the courts should not review the merits of an arbitrator’s decision pursuant to a collective bargaining agreement, even if a party alleges that the arbitrator's decision rests on errors of fact or law.
See Major League Baseball Players Association v. Garvey,
. The Union also asked the arbitrator to clarify one issue that does not appear to be directly related to the calculation of Brown’s back pay award. The Union asked the arbitrator to make it clear that Witco should expunge Brown’s disciplinary record in accordance with the provisions of the collective bargaining agreement. In his August 27 Clarification Letter, the arbitrator indicated that, consistent with the terms of the collective bargain
. Brown's enforcement action arises under § 301 of the Labor Management Relations Act, 29 U.S.C. § 185(a), because Brown’s claim requires the court to interpret his rights under a collective bargaining agreement and determine whether the agreement has been breached.
See Carrion v. Enterprise Ass’n,
. The magistrate also stated that the arbitrator could receive whatever evidence the arbitrator considered appropriate and necessary tct make the clarification specified in the remand order.
. Brown does not appear to allege or argue that the Union breached its duty of fair representation either by requesting clarification from the arbitrator or by failing to oppose Witco’s request for clarification. Accordingly, the Union’s actions in the course of the arbitration can fairly be attributed to Brown.
. Courts may rely on the FAA for guidance in reviewing an arbitration award arising under a collective bargaining agreement and Section 301 of the LMRA, but courts are not obligated to follow the FAA in every technical detail.
