Notwithstanding any provision of a charter of a town or any other law, a town council may establish the compensation to be paid to council members and the mayor. No increase in salary of a council member or mayor shall take effect during the incumbent council member’s or mayor’s term in office; however, this restriction shall not apply to councils or mayors when the council members are elected for staggered terms. In addition to salary, each member of the council and the mayor of any town may be compensated with such benefits as are provided town employees by the town.
