How to calculate the FMLA rolling year method

Abstract: FMLA regulations define four different methods that an employer may use to determine the amount of FMLA leave an employee has used within a 12 month period under the Act. The most commonly used method is the rolling year or look-back method. The employer will look back over the last 12 months and subtract the total time the employee has used from the employee's 12 week leave allotment.
