In California. I would like to know that while I am receiving a check under disability or Workers compensation, is it okay for me to also receive a check for vac or sick cash out from my company. Will this affect me in the future if I get audited b/c at the same period I am receiving both checks from the company and the state of disability? OR should I request for the company to hold onto it until i return to full duty?

Please help! thanks.

Based on what I have found, you have the option to receive or not receive vacation pay while receiving worker comp disablity payments. This is an election that you should have made on a HR form, likely at the time of hire or reporting of disability. Some employers use sick and vacation days to provide pay for the interim until the disability payments can start.
