Appeal from a decision of the Workers’ Compensation Board, filed May 5, 2005, which ruled that claimant voluntarily withdrew from the labor market and denied his claim for workers’ compensation benefits.
The Workers’ Compensation Board found that claimant suffers occupational asbestos-related pleural disease, he has a permanent partial disability, this disability was a factor contributing to his early retirement with a reduced pension at the age of 55, and his withdrawal from the workforce at that time was therefore involuntary. These findings are not in dispute. Despite the Board’s recognition that claimant’s retirement was involuntary, however, it concluded that claimant voluntarily withdrew from, and was not attached to, the labor market as of the date of his retirement because he admitted that he had not sought work within his physical restrictions postretirement. Finding that this shifted the burden to claimant to prove that his reduced earning capacity continued to be due to his disability, the Board denied the claim for workers’ compensation benefits. Claimant appeals, contending that the Board erred as a matter of law by viewing his testimony that he had not sought postretirement work within his physical restrictions as defeating the inference that his permanent partial disability continued to contribute to his subsequent reduced earning capacity.
While the Board properly found that claimant’s decision to retire was due, at least in part, to his work-related permanent partial disability, and his retirement was, therefore, an involuntary withdrawal from the labor market, it erred in then concluding that claimant’s failure to seek employment within his physical limitations after the date of his retirement made his withdrawal voluntary (see Matter of Pittman v ABM Indus., Inc., 24 AD3d 1056, 1057 [2005]). As we explained in Pittman, *1201the Board’s initial determination that claimant’s retirement was involuntary gave rise to an inference that his reduced earning capacity continued after retirement. To overcome the inference, there must then be direct and positive proof that something other than the disability was the sole cause of his postretirement reduced earning capacity. “Claimant’s testimony that [he] had not looked for work after retiring did not defeat the inference that [his] partial disability continued to contribute to [his] reduced earning capacity, as there is no evidence that the failure to seek employment was the sole cause of the subsequent reduction” (id. at 1058; see Matter of Leeber v LILCO, 29 AD3d 1198 [2006] [decided herewith]; Matter of Jiminez v Waldbaums, 9 AD3d 99, 100 [2004]).
