an a person lose vacation days due to being inactive while recovering from a work related injury under Ky law

If a worker is off work -- for any reason -- then an employer has no obligation under Kentucky workers' compensation laws to continue any employer provided benefits, i.e., health insurance, holiday pay, 401(k) match, accruing additional vacation days, etc. An employer cannot revoke previously vested benefits.  As for previously accrued vacation days, if the employer has a policy previously in effect that requires vacation days to be used within a certain time frame or limits the number of days that can be accrued, then that policy is enforceable. Please understand that there is no legal obligation for an employer to provide any vacation days or vacation pay. The exception is if there is a collective bargaining agreement or some other written employment contact that specifically addresses the issue of vacation days.
