29 CFR § 825.200 - Amount of leave.
(a) Except in the case of leave to care for a covered servicemember with a serious injury or illness, an eligible employee's FMLA leave entitlement is limited to a total of 12 workweeks of leave during any 12-month period for any one, or more, of the following reasons:
(5) Because of any qualifying exigency arising out of the fact that the employee's spouse, son, daughter, or parent is a military member on covered active duty status (or has been notified of an impending call or order to covered active duty).
(b) An employer is permitted to choose any one of the following methods for determining the 12-month period in which the 12 weeks of leave entitlement described in paragraph (a) of this section occurs:
(1) The calendar year;
(3) The 12-month period measured forward from the date any employee's first FMLA leave under paragraph (a) begins; or,
(4) A “rolling” 12-month period measured backward from the date an employee uses any FMLA leave as described in paragraph (a).
(c) Under methods in paragraphs (b)(1) and (b)(2) of this section an employee would be entitled to up to 12 weeks of FMLA leave at any time in the fixed 12-month period selected. An employee could, therefore, take 12 weeks of leave at the end of the year and 12 weeks at the beginning of the following year. Under the method in paragraph (b)(3) of this section, an employee would be entitled to 12 weeks of leave during the year beginning on the first date FMLA leave is taken; the next 12-month period would begin the first time FMLA leave is taken after completion of any previous 12-month period. Under the method in paragraph (b)(4) of this section, the “rolling” 12-month period, each time an employee takes FMLA leave the remaining leave entitlement would be any balance of the 12 weeks which has not been used during the immediately preceding 12 months. For example, if an employee has taken eight weeks of leave during the past 12 months, an additional four weeks of leave could be taken. If an employee used four weeks beginning February 1, 2008, four weeks beginning June 1, 2008, and four weeks beginning December 1, 2008, the employee would not be entitled to any additional leave until February 1, 2009. However, beginning on February 1, 2009, the employee would again be eligible to take FMLA leave, recouping the right to take the leave in the same manner and amounts in which it was used in the previous year. Thus, the employee would recoup (and be entitled to use) one additional day of FMLA leave each day for four weeks, commencing February 1, 2009. The employee would also begin to recoup additional days beginning on June 1, 2009, and additional days beginning on December 1, 2009. Accordingly, employers using the rolling 12-month period may need to calculate whether the employee is entitled to take FMLA leave each time that leave is requested, and employees taking FMLA leave on such a basis may fall in and out of FMLA protection based on their FMLA usage in the prior 12 months. For example, in the example above, if the employee needs six weeks of leave for a serious health condition commencing February 1, 2009, only the first four weeks of the leave would be FMLA protected.
(1) Employers will be allowed to choose any one of the alternatives in paragraph (b) of this section for the leave entitlements described in paragraph (a) of this section provided the alternative chosen is applied consistently and uniformly to all employees. An employer wishing to change to another alternative is required to give at least 60 days notice to all employees, and the transition must take place in such a way that the employees retain the full benefit of 12 weeks of leave under whichever method affords the greatest benefit to the employee. Under no circumstances may a new method be implemented in order to avoid the Act's leave requirements.
(2) An exception to this required uniformity would apply in the case of a multi-State employer who has eligible employees in a State which has a family and medical leave statute. The State may require a single method of determining the period during which use of the leave entitlement is measured. This method may conflict with the method chosen by the employer to determine any 12 months for purposes of the Federal statute. The employer may comply with the State provision for all employees employed within that State, and uniformly use another method provided by this regulation for the leave entitlements described in paragraph (a) for all other employees.
(e) If an employer fails to select one of the options in paragraph (b) of this section for measuring the 12-month period for the leave entitlements described in paragraph (a), the option that provides the most beneficial outcome for the employee will be used. The employer may subsequently select an option only by providing the 60-day notice to all employees of the option the employer intends to implement. During the running of the 60-day period any other employee who needs FMLA leave may use the option providing the most beneficial outcome to that employee. At the conclusion of the 60-day period the employer may implement the selected option.
(f) An eligible employee's FMLA leave entitlement is limited to a total of 26 workweeks of leave during a single 12-month period to care for a covered servicemember with a serious injury or illness. An employer shall determine the single 12-month period in which the 26-weeks-of-leave-entitlement described in this paragraph occurs using the 12-month period measured forward from the date an employee's first FMLA leave to care for the covered servicemember begins. See § 825.127(e)(1).
(g) During the single 12-month period described in paragraph (f), an eligible employee's FMLA leave entitlement is limited to a combined total of 26 workweeks of FMLA leave for any qualifying reason. See § 825.127(e)(3).
(h) For purposes of determining the amount of leave used by an employee, the fact that a holiday may occur within the week taken as FMLA leave has no effect; the week is counted as a week of FMLA leave. However, if an employee is using FMLA leave in increments of less than one week, the holiday will not count against the employee's FMLA entitlement unless the employee was otherwise scheduled and expected to work during the holiday. Similarly, if for some reason the employer's business activity has temporarily ceased and employees generally are not expected to report for work for one or more weeks (e.g., a school closing two weeks for the Christmas/New Year holiday or the summer vacation or an employer closing the plant for retooling or repairs), the days the employer's activities have ceased do not count against the employee's FMLA leave entitlement. Methods for determining an employee's 12-week leave entitlement are also described in § 825.205. See § 825.802 for special calculation of leave rules applicable to airline flight crew employees.
