Subject to section 6383, an employee shall be entitled to a total of 12 administrative workweeks of leave during any 12-month period for one or more of the following:

Subject to section 6383, an employee shall be entitled to a total of 12 administrative workweeks of leave during any 12-month period for one or more of the following:

(A) Because of the birth of a son or daughter of the employee and in order to care for such son or daughter.

(B) Because of the placement of a son or daughter with the employee for adoption or foster care.

(C) In order to care for the spouse, or a son, daughter, or parent, of the employee, if such spouse, son, daughter, or parent has a serious health condition.

(D) Because of a serious health condition that makes the employee unable to perform the functions of the employee’s position.

(E) Because of any qualifying exigency arising out of the fact that the spouse, or a son, daughter, or parent of the employee is on covered active duty (or has been notified of an impending call or order to covered active duty) in the Armed Forces.

(2) The entitlement to leave under subparagraph (A) or (B) of paragraph (1) based on the birth or placement of a son or daughter shall expire at the end of the 12-month period beginning on the date of such birth or placement.

(3) Subject to section 6383, an employee who is the spouse, son, daughter, parent, or next of kin of a covered servicemember shall be entitled to a total of 26 administrative workweeks of leave during a 12-month period to care for the servicemember. The leave described in this paragraph shall only be available during a single 12-month period.

(4) During the single 12-month period described in paragraph (3), an employee shall be entitled to a combined total of 26 administrative workweeks of leave under paragraphs (1) and (3). Nothing in this paragraph shall be construed to limit the availability of leave under paragraph (1) during any other 12-month period.

If an employee requests intermittent leave, or leave on a reduced leave schedule, under subparagraph (C) or (D) of subsection (a)(1) or under subsection (a)(3), that is foreseeable based on planned medical treatment, the employing agency may require such employee to transfer temporarily to an available alternative position offered by the employing agency for which the employee is qualified and that—

(1) Leave under subparagraph (A) or (B) of subsection (a)(1) shall not be taken by an employee intermittently or on a reduced leave schedule unless the employee and the employing agency of the employee agree otherwise. Subject to paragraph (2), subsection (e)(2), and subsection (b)(5) or (f) (as appropriate) of section 6383, leave under subparagraph (C) or (D) of subsection (a)(1) or under subsection (a)(3) may be taken intermittently or on a reduced leave schedule when medically necessary. Subject to subsection (e)(3) and section 6383(f), leave under subsection (a)(1)(E) may be taken intermittently or on a reduced leave schedule. In the case of an employee who takes leave intermittently or on a reduced leave schedule pursuant to this paragraph, any hours of leave so taken by such employee shall be subtracted from the total amount of leave remaining available to such employee under subsection (a), for purposes of the 12-month period involved, on an hour-for-hour basis.

If an employee requests intermittent leave, or leave on a reduced leave schedule, under subparagraph (C) or (D) of subsection (a)(1) or under subsection (a)(3), that is foreseeable based on planned medical treatment, the employing agency may require such employee to transfer temporarily to an available alternative position offered by the employing agency for which the employee is qualified and that—

(A) has equivalent pay and benefits; and

(B) better accommodates recurring periods of leave than the regular employment position of the employee.

Except as provided in subsection (d), leave granted under subsection (a) shall be leave without pay.

An employee may elect to substitute for leave under subparagraph (A), (B), (C), (D), or (E) of subsection (a)(1) any of the employee’s accrued or accumulated annual or sick leave under subchapter I for any part of the 12-week period of leave under such subsection, except that nothing in this subchapter shall require an employing agency to provide paid sick leave in any situation in which such employing agency would not normally provide any such paid leave. An employee may elect to substitute for leave under subsection (a)(3) any of the employee’s accrued or accumulated annual or sick leave under subchapter I for any part of the 26-week period of leave under such subsection.

In any case in which the necessity for leave under subparagraph (C) or (D) of subsection (a)(1) or under subsection (a)(3) is foreseeable based on planned medical treatment, the employee—

(1) In any case in which the necessity for leave under subparagraph (A) or (B) of subsection (a)(1) or under subsection (a)(3) is foreseeable based on an expected birth or placement, the employee shall provide the employing agency with not less than 30 days’ notice, before the date the leave is to begin, of the employee’s intention to take leave under such subparagraph, except that if the date of the birth or placement requires leave to begin in less than 30 days, the employee shall provide such notice as is practicable.

In any case in which the necessity for leave under subparagraph (C) or (D) of subsection (a)(1) or under subsection (a)(3) is foreseeable based on planned medical treatment, the employee—

(A) shall make a reasonable effort to schedule the treatment so as not to disrupt unduly the operations of the employing agency, subject to the approval of the health care provider of the employee or the health care provider of the son, daughter, spouse, parent, or covered servicemember of the employee, as appropriate; and

(B) shall provide the employing agency with not less than 30 days’ notice, before the date the leave is to begin, of the employee’s intention to take leave under such subparagraph, except that if the date of the treatment requires leave to begin in less than 30 days, the employee shall provide such notice as is practicable.

(3) In any case in which the necessity for leave under subsection (a)(1)(E) is foreseeable, whether because the spouse, or a son, daughter, or parent, of the employee is on covered active duty, or because of notification of an impending call or order to covered active duty, the employee shall provide such notice to the employer as is reasonable and practicable.
