You (not the employee) determine FMLA leave

Q. At a recent FMLA seminar I attended, the speaker said that employers have the responsibility to ask employees if they want their absences applied to their 12 weeks of available FMLA leave. I understand that we can run FMLA leave concurrent with paid sick leave, but what if an employee doesn’t want to use up his FMLA leave and has other paid or unpaid leave available under our company leave policy?—J.G., Ohio
