28 CFR §301.204

1. (a)Once approved, the inmate shall receive lost-time wages until the inmate:
   1. (1)Is released;
   2. (2)Is transferred to another institution for reasons unrelated to the work injury;
   3. (3)Returns to the pre-injury work assignment;
   4. (4)Is reassigned to another work area or program for reasons unrelated to the sustained work injury, or is placed into Disciplinary Segregation; or,
   5. (5)Refuses to return to a regular work assignment or to a lighter duty work assignment after medical certification of fitness for such duty.
2. (b)An inmate medically certified as fit for return to work shall sustain no monetary loss due to a required change in work assignment. Where there is no light duty or regular work assignment available at the same rate of pay as the inmate's pre-injury work assignment, the difference shall be paid in lost-time wages. Lost-time wages are paid until a light duty or regular work assignment at the same pay rate as the inmate's pre-injury work assignment is available.
