My medical condition limits me to work 40 hour workweek but my employer has assigned me to work eight hours of overtime in a week. Can I take FMLA leave for the overtime?

Yes. Employees with proper medical certifications may use FMLA leave in lieu of
working required overtime hours. The regulations clarify that the hours that an employee
would have been required to work but for the taking of FMLA leave can be counted
against the employee’s FMLA entitlement. Employers must select employees for
required overtime in a manner that does not discriminate against workers who need to use
FMLA leave.
