Should I have to be on fmla if I’m workman’s comp

FMLA and workers' compensation are two completely different things.  FMLA is unpaid leave for certain specific health conditions.  This can include a work-related injury, but usually is an other health condition, and may be a health condition of another member of your family. Workers' compensation pays medical expenses, temporary income benefits (TIBs), and impairment income benefits (IIBs) caused by a work-related injury.  If your health care provider has not released you to return to work after a work-related injury, your employer cannot terminate you.  If your health care provider has released you to return to work without restrictions after a work-related injury, your employer can only terminate you if you fail to report to work.
