Workers fail to give FMLA proof? Cut ‘Em loose

Q. One of our employees had been out sick for two months. We’ve received a doctor’s note that just says he’s unable to work and that a return date is undetermined. We faxed and mailed FMLA paperwork, but it hasn’t been returned. Meanwhile, the employee is receiving disability benefits through our short-term disability plan. How do we calculate the start of FMLA leave? From the date the disability payment began? And if we never get the FMLA paperwork back, can we terminate him? —T.B., Tennessee
