LEGISLATIVE LEAVE.

(a) A fire fighter or police officer is entitled to legislative leave without pay to appear before or to petition a governmental body during a regular or special session of that body as prescribed by this section.

(b) To be eligible for legislative leave, a fire fighter or police officer must submit a written application to the municipality on or before the 30th day before the date the fire fighter or police officer intends to begin the legislative leave. The application must indicate the length of the requested leave and state that the fire fighter or police officer is willing to reimburse the municipality for any wages, pension, or other costs the municipality will incur as a result of the leave. The length of the requested leave may not exceed the length of the session.

(c) Within 30 days after the date the municipality receives the application, the municipality shall notify the fire fighter or police officer in writing of the actual amount of money required to offset the costs the municipality will incur. The municipality may require the fire fighter or police officer to post the money before granting the leave.

(d) The municipality shall grant legislative leave to a fire fighter or police officer who submits an application as prescribed by this section and who complies with any requirement relating to payment of costs unless an emergency exists or unless granting the leave will result in an insufficient number of employees to carry out the normal functions of the fire or police department.

(e) If the head of the fire or police department determines that granting a legislative leave will result in an insufficient number of employees to carry out the normal functions of the department, another fire fighter or police officer may volunteer to work in the applicant's place on an exchange of time basis as long as no overtime results. If a fire fighter or police officer volunteers to work in the applicant's place and no overtime will result, the department head shall allow the volunteer to work for the applicant. If the volunteer work will solve the problem of having an insufficient number of employees, the municipality shall grant the legislative leave.

(f) Legislative leave may not be construed as a break in service for any purpose, including the determination of seniority, promotions, sick leave, vacations, or retirement.

(g) Legislative leave granted under this section to a fire fighter or police officer to attend a session of the Congress of the United States shall be granted for a period not to exceed 30 percent of the applicant's total annual working days during each year in which leave is requested.
