Opinion by
Judge Palladino,Kenneth Hoffman (Claimant) is a token claimant seeking review of an order of the Unemployment Compensation Board of Review (Board) denying benefits to himself and similarly situated members of the International Association of Machinists and Aerospace Workers, Local 1842 (Union). The Board reversed the referees award of benefits, and determined that Claimant and other union members were precluded by Section 402(d) *266of the Unemployment Compensation Law (Act)1 from receiving benefits. Section 402(d) of the Act bars a claimant from compensation for any week in which his unemployment was due to a stoppage of work existing because of a labor dispute, other than a lockout, at the factory, establishment, or other premises at which the claimant is or was last employed.2
The Union and intervenor-employer, Joy Manufacturing Company (Employer), were parties to a collective bargaining agreement (prior contract) which expired on August 6, 1983. The Union represented employees at several mining machinery manufacturing plants in Franklin, Pennsylvania, owned by Employer. The parties bargained from June 7, 1983, until August 1, 1983, without a new agreement being formulated.
A formal strike was voted on, assented to, and commenced as of midnight, August 6, 1983 and pickets were set up. After four weeks, Employer began dismantling the plant and relocating the manufacturing work to other plant locations and subcontractors in Pennsylvania, West Virginia, Virginia, Illinois, Colorado, New Hampshire, and Michigan.
On October 19, 1983, a negotiation session was held at which the Union made offers to resume work either under a new one-year contract based on the terms and conditions of the prior contract or under the terms of the prior contract on a day-to-day basis while negotiations continued. These offers were rejected by Employer. The strike was finally settled November 20, 1983.
Claimant seeks benefits covering the compensable week ending October 29, 1983, and subsequent there*267to,3 4alleging that the Unions offer to return to work and Employers subsequent rejection of that offer had sufficed to convert the strike into a lockout for the purposes of Section 402(d) of the Act. The referee awarded benefits and the Board reversed. Claimant now appeals to this Court. We affirm the Boards order.
The question of whether the work stoppages resulted from a strike or lockout is a mixed question of law and feet subject to this Courts review. Bishop v. Unemployment Compensation Board of Review, 90 Pa. Commonwealth Ct. 553, 496 A.2d 110 (1985). When a claimants employment is interrupted by a work stoppage arising from a labor dispute, the claimant bears the burden of proving that a lockout caused the stoppage. Id.4 Where the employees have struck first, a claimant may still show that the strike was precipitated by an employers unilateral change in the status quo or may show that the employers subsequent change in status quo converted the strike into a lockout for purposés of Section 402(d) of the Act. See Norwin School District v. Unemployment Compensation Board of Review, 80 Pa. Commonwealth Ct. 67, 471 A.2d 904 (1984), aff'd, 510 Pa. 255, 507 A.2d 373 (1986); High v. Unemployment Compensation Board of Review, 67 Pa. Commonwealth *268Ct. 472, 447 A.2d 701 (1982), aff'd, 505 Pa. 379, 479 A.2d 967 (1984); Unemployment Compensation Board of Review v. Sun Oil Co., 476 Pa. 589, 383 A.2d 519 (1978), appeal dismissed, 440 U.S. 977 (1979).
The determination as to which party was responsible for the initial disruption of the status quo does not end the inquiry. Determinations of benefit eligibility under Section 402(d) of the Act should be made on a week-by-week basis. See Norwin, 80 Pa. at 75, 507 A.2d at 382; High, 505 Pa. at 383, 479 A.2d at 969. Compare Westinghouse Electric Corporation v. Unemployment Compensation Board of Review, 187 Pa. Superior Ct. 403, 413-14, 144 A.2d 679, 684 (1958); Vrotney Unemployment Compensation Case, 400 Pa. 440, 163 A.2d 91 (1960). The distinction between a strike and a lockout is judged by reference to whether the union or the employer first refused to continue the employment relationship under the terms and conditions of the employment as they existed just before the expiration of the prior collective bargaining agreement. A strike may be converted to a lockout for purposes of Section 402(d) of the Act when an employer refuses to accept a unions offer to work for a reasonable period of time under the status quo conditions pending negotiation of a new contract. See High, 505 Pa. at 382-83, 479 A.2d at 968-69; High, 67 Pa. Commonwealth Ct. at 477-78, 447 A.2d at 704-05; Odgers v. Unemployment Compensation Board of Review, 89 Pa. Commonwealth Ct. 439, 450, n.10, 492 A.2d 808, 814, n.10 (1985).
In the case at bar it is undisputed that the Union first refused to continue working under the status quo when it went out on strike at the expiration of the prior contract on August 6, 1983. The Board found, and its findings are supported by substantial evidence in the record, that Employer maintained partially finished work in the plant for approximately four weeks after the *269commencement of the strike in the hopes that the labor dispute would be resolved during that period. During that four week period, work was available to the striking employees on a day-to-day basis. When no resolution was forthcoming in that period of time, Employer made an economic decision to transfer the partially completed work to other plants for completion. Once the work was shipped out, it was not possible for Employer to recall it and Employer required a minimum of two days start-up time to resume operations at the plant. The Board also found that Employer rejected the Unions October 19, 1983 offer to return to work on a day-to-day basis because at that time it would not have been practical for Employer to operate its plant on a day-to-day basis.
Claimant argues that the rejection by Employer of the Unions offer constitutes a refusal by Employer to permit work to continue for a reasonable time under the status quo, and, therefore, converts the strike into a lockout under the principles enunciated in Vrotney, High, and Nortoin. We disagree.
In view of the fact that almost three months elapsed from the time that the Union went out on strike until it offered to resume work under the status quo, and that Employer found it economically necessary to reassign the work in progress during the strike, we do not believe that the Unions offer to resume work on a day-today basis was an offer to work for a reasonable time. We have held that what constitutes a “reasonable time” varies depending on the particular circumstances of each case. McKeesport Area School District v. Unemployment Compensation Board of Review, 40 Pa. Commonwealth Ct. 334, 397 A.2d 458 (1979) (holding that day-to-day extension is not unreasonable for teachers) citing Hershey Estates v. Unemployment Compensation Board of Review, 400 Pa. 446, 163 A.2d 535 (1960) (holding that day-to-day extension was not rea*270sonable for employees involved in a service industry). We conclude that a day-to-day extension of the status quo would not be reasonable under the facts of this case as found by the Board and enunciated above.
Additionally, based upon our review of the record, we conclude that the Unions offer to resume work for a period of one year was not an offer to continue the status quo pending negotiations; rather, it was an offer for a new one-year contract on the same terms and conditions as the prior contract. As such, this offer did not satisfy the Unions burden of proving that it offered to continue working under the status quo for a reasonable period pending final settlement of negotiations. See Bishop, 90 Pa. Commonwealth Ct. at 559, 496 A.2d at 113 (1985).
Accordingly, we affirm the Boards order denying benefits.
Order
And Now, September 3, 1986, the order of the Unemployment Compensation Board of Review at No. B-240432, dated May 17, 1985, is affirmed.
Act of December 5, 1936, Second Ex. Sess., P.L. (1937) 2897, as amended, 43 P.S. §802(d).
See 43 P.S. §802(d).
On August 24, 1983 the Office of Employment Security issued a determination denying benefits on the basis that the initial work stoppage was a strike. This determination was affirmed by a referee and the Board. No appeal was taken from that decision to this Court.
Because Claimant had the burden of proof and did not prevail before the Board, our scope of review is limited to determining whether the Board s findings of fact are consistent with each other and with the conclusions of law and can be sustained without a capricious disregard of competent evidence or whether an error of law was made by the Board.
