The governing body of any county, city, or town may empower the fire department therein to make bylaws to promote its objects consistent with the laws of the Commonwealth and ordinances of the county, city, or town and may provide for the compensation of the officers and employees of such department. All check stubs or time cards purporting to be a record of time spent on the job by a firefighter shall record all hours of employment, regardless of how spent. All check stubs or pay records purporting to show the hourly compensation of a firefighter shall show the actual hourly wage to be paid. Nothing in this section shall require the showing of such information on check stubs, time cards, or pay records; however, if such information is shown, the information shall be in compliance with this section.
