FMLA FAQ: How Many Intermittent FMLA Leave Hours is an FLSA-Exempt Employee Entitled To?

Q. We employ an FLSA-exempt employee who has been certified for intermittent FMLA leave for migraine headaches. He averages two to three intermittent absences per month. Normally, I would calculate the employee’s total FMLA allotment as 480 FMLA hours (12 weeks x 40 hrs/wk), but he claims he should be entitled to 600 FMLA hours because he averages 50 hours worked per week. Is he correct? Help!?!
