Under 5 U.S.C. 8104(a), OWCP may direct a permanently disabled employee to undergo vocational rehabilitation. To ensure that vocational rehabilitation services are available to all who might be entitled to benefit from them, an injured employee who has a loss of wage-earning capacity shall be presumed to be “permanently disabled,” for purposes of this section only, unless and until the employee proves that the disability is not permanent. If an employee without good cause fails or refuses to apply for, undergo, participate in, or continue to participate in a vocational rehabilitation effort when so directed, OWCP will act as follows:

(a) Where a suitable job has been identified, OWCP will reduce the employee's future monetary compensation based on the amount which would likely have been his or her wage-earning capacity had he or she undergone vocational rehabilitation. OWCP will determine this amount in accordance with the job identified through the vocational rehabilitation planning process, which includes meetings with the OWCP nurse and the employer. The reduction will remain in effect until such time as the employee acts in good faith to comply with the direction of OWCP.

(b) Where a suitable job has not been identified, because the failure or refusal occurred in the early but necessary stages of a vocational rehabilitation effort (that is, interviews, testing, counseling, functional capacity evaluations, and work evaluations), OWCP cannot determine what would have been the employee's wage-earning capacity.

(c) Under the circumstances identified in paragraph (b) of this section, in the absence of evidence to the contrary, OWCP will assume that the vocational rehabilitation effort would have resulted in a return to work with no loss of wage-earning capacity, and OWCP will reduce the employee's monetary compensation accordingly (that is, to zero). This reduction will remain in effect until such time as the employee acts in good faith to comply with the direction of OWCP.
