Kauffman sued his employer, International Brotherhood of Teamsters (hereafter IBT), in Superior Court for breach of an agreement to provide him with a monthly housing allowance. IBT had paid Kauffman the allowance starting in 1993, but in April 1996 discontinued it, prompting this suit. IBT defended by arguing in part that, as an at-will employee, Kauff-man had impliedly agreed to elimination of the housing allowance by remaining an employee of IBT for years (namely, three) after the change took effect with his knowledge. The trial court, implicitly relying on our decision in
National Rifle Ass’n v. Ailes,
*46 I.
Beginning in 1992, Kauffman took a leave of absеnce from his job with United Parcel Service in New Jersey to become an International Representative for IBT. IBT did not specify a period of time during which Kauffman would be employed by IBT, and his leave from UPS was to be active “as long as [he] wanted.” 1 IBT’s constitution provided that the Generаl President could remove an International Representative “when he deems it for the best interests of the International Union.” In 1993, Mario Perrucci, an IBT representative, asked Kauffman to relocate to Washington, D.C. Perrucci agreed that IBT would compensate Kauffman to offset the higher cost of living in Washington. Specifically, IBT offered to reimburse his housing expenses, and Kauffman accepted this offer as a condition of his agreement to relocate. Kauffman maintained his home in New Jersey as his permanent residence and obtained an apartmеnt in Washington. IBT reimbursed him for his housing expenses in Washington until late 1994.
On December 15, 1994, IBT changed its policy somewhat and decided to pay Kauff-man a monthly housing allowance of one thousand dollars, which would be included in the last paycheck of each month to cover expenses for thе following month. In 1994, Kauffman still owned his home in New Jersey, but spent all of his time in Washington because of his assignment and because he and his wife had divorced. On July 29, 1995, Kauffman requested that IBT change his permanent address to a residence in Arlington, Virginia.
Around April 9,1996, Kauffman received a memorandum from Howard Edwards, Director of Human Resources for IBT, notifying him that he “no longer qualified]” for the housing allowance because he had relocated his permanent residence to the Washington, D.C. area (i.e., he would no longer be forced to maintain two residences), and that the allowance would bе discontinued effective April l. 2 The memorandum instructed him to contact Edwards if he had questions. Kauffman requested to meet with Aaron Belk, who was “party to the discussion and the agreement,” but never obtained a meeting. Kauffman spoke to Edwards, who “reemphasized what the memo said.” Kauffman also raised the issue in a meeting with a director and the office staff and sent mem-oranda. He understood, nevertheless, that IBT was no longer going to pay the housing allowance. IBT never changed its position and did not pay the allowance after April 1996. Kauffman sued in Superior Court on Mаrch 29, 1999, and IBT terminated his employment the next day. 3
II.
Kauffman does not challenge his discharge as an employee by IBT in 1999.
*47
He does not, that is, dispute the fact that he was an “at-will” employee of IBT, a relationship “terminable ... by either party at any time.”
Nickens v. Labor Agency of Metro. Washington,
In
Ailes
a number of employees who had been discharged as part of a reduction-in-force sued to recover monetary compensation for unused leave they had accrued in excess of a 225-hour limit that NRA had imposed by a policy change made during their employment. On the employer’s appeal from an adverse jury verdict, this court agreed with the plaintiffs that, “as a general rule, an employee whо accrues but does not take ... paid leave is entitled to monetary compensation for that leave upon discharge ... absent an agreement to the contrary.”
Ailes,
Ailes
did not expressly confine itself to agreement by at-will employees, though we think that is its clear implication.

So
*48
viewed, the principle
Ailes
established for this jurisdiction is in keeping with the rule adopted by most courts considering the issue that an employer may prospectively modify the terms of at-will еmployment and that the employee’s continued service amounts to acceptance of the modification.
See Cotter v. Desert Palace, Inc.,
Contrary to Kauffman’s argument, contract mоdifications in this context are not unilateral and without consideration. Rather, unlike employment contracts for a fixed duration, neither party to at-will employment is bound to continue performance, and thus courts properly view future performance by each as valid consideration for the change in terms.
See Curtis 1000, Inc. v. Suess,
In his deposition, Kauffman admitted that he knew IBT would no longer pay the housing allowance beginning in 1996, and yet he continued the employment for three more years — by any measure “a reasonable period during which” to consider his “personal alternatives,”
i.e.,
“whether to resign ... or to remain with [IBT].”
Ailes,
Kauffman cites decisions recognizing the right of at-will employees to sue for breach of a subsidiary agreement, say, to pay accrued commissions or bonuses.
See, e.g., Smith v. Chase Group, Inc.,
A.2d at 820. It is worth noting, moreover, that IBT’s modification operated only prospectively and did not seek to recoup any “accrued” housing payments to Kauffman.
As an alternative to his breach of contract claim, Kauffman invokes the doctrine of promissory estoppel, but to the extent he explains its application here at all, 7 it appears merely to restate his breach of contract claim in othеr dress. Kauffman cites no promise on which he relied to his detriment other than the same term IBT was free to modify with his consent— a consent implied from his continuing to work for IBT as an at-will employee. (He does not claim, for example, that IBT induced him to move to Washington permanently, such that he incurred costs he could not meet through his salary and his savings in no longer having to keep a second, New Jersey home.) Kauffman, in short, offers no reason why rejection of his breach of contract claim under the principles we have discussed results in an “injustice.” Bender, supra note 7.
Finally, we reject Kauffman’s argument that the law of the case doctrine prevented the trial judge from granting IBT’s motion for summary judgment. More than once this court has cited the
*50
principle that “we cannot be expected to reverse a correct decision by one [trial] judge simply because we find it contrary to a prior ruling by another [trial] judge in the same case,
i.e.,
contrary to the law of the case.”
Williams v. Paul,
Accordingly, the judgment of the Superior Court is
Affirmed.
Notes
. Although Kauffman alleged in his complaint that his appointment was "[i]n accordance with the collective bargaining agreement between UPS and [IBT],” Kauffman produced no evidence of these agreements.
. Since the allowance for April would have been paid on March 31, 1996, it would not be affected by the April 1 effective date. Kauff-man conceded at oral argument that the change had only prospective effect.
.After Kauffman filed his suit, IBT moved unsuccessfully for judgment on the pleadings, see Super. Ct. Civ. R. 12(c), then moved for summary judgment at the close of discovery. The trial court denied the motion and subsequently granted the parties' joint motion to stay further proceedings pending the outcome of a suit Kauffman had filed meаnwhile in federal court. See note 4, infra. After that suit was resolved, IBT successfully renewed its motion for summary judgment in Superior Court, giving rise to this appeal.
.
See, e.g.,
Br. for App. at 11 ("Analysis of the instant case ... is not altered when one adds the fact of Appellant’s at will status.”). Kauff-man’s at-will status was, in any event, establishеd conclusively in the related suit he brought in federal district court,
see Kauffman v. International Bhd. of Teamsters, AFL-CIO,
Civ. Act. No. 01-1104 (D.D.C.) (Order of May 24, 2005), a decision he did not appeal.
See, e.g., Smith v. Jenkins,
. In
Dahl v. Brunswick Corp.,
. Of course, if the employer’s notice of change required the employee’s acceptance by signature,
see Schoppert,
. For promissory estoppel to lie, "there must be evidence of a promise, the promise must reasonably induce reliance upon it, and the promise must be relied upon to the detriment of the promisee.”
