Wash. Admin. Code § 192-190-040
(1) "Back pay" means wages paid to a worker for a prior pay period. An employer may award back pay to a separated or suspended employee for a specific period of time.
If you received benefits for any weeks for which back pay is awarded, you must report the amount of the back pay to the department.
(2) A back pay award may not be used to purge a disqualifying separation.
A lump sum payment of worker's compensation benefits does not constitute a back pay award for purposes of RCW 50.20.160.
