Any such written authorization may be withdrawn by such officer or employee or member at any time upon filing written notice of such withdrawal with the fiscal or disbursing officer. The provisions of this section shall apply to and be effective within every city, county, town, village, school district and organized public district in the state.

The sum to be paid by it under such plan, in the discretion of the municipal corporation, may be any percentage of the total cost, including the whole thereof. For the purposes of this section, the term employee shall include the volunteer firefighters of the municipality or fire district or employees, commissioners, or officers of a town improvement district governed by a separate board of commissioners.
