Overtime. If an employee would normally be required to work overtime, but is unable to do so because of a FMLA-qualifying reason that limits the employee's ability to work overtime, the hours which the employee would have been required to work may be counted against the employee's FMLA entitlement. In such a case, the employee is using intermittent or reduced schedule leave. For example, if an employee would normally be required to work for 48 hours in a particular week, but due to a serious health condition the employee is unable to work more than 40 hours that week, the employee would utilize eight hours of FMLA-protected leave out of the 48-hour workweek, or one-sixth ( 1/6) of a week of FMLA leave. Voluntary overtime hours that an employee does not work due to an FMLA-qualifying reason may not be counted against the employee's FMLA leave entitlement.
