Worker's Compensation Leave

dblum

We have an employee who has been out on worker's compensation leave since last May.  It is questionable whether his medical condition was caused by t he relatively minor injury he received on the job; although I suppose that's actually a side issue.  My question is how long do we need to keep him employed?  He cannot work at all, not even light-duty.  We have been keeping on our health insurance, with him paying his portion of the premium.  Certainly, FMLA ran out a long time ago.  When can we terminate him?  Thanks!
