Some of Providence’s highest-ranking officials – including the mayor, every member of the City Council and the chiefs of the police and fire departments – could be in line for pay raises under a proposal set to be put forth by a panel reviewing salaries in city government. Providence’s five-member Salary Review Commission does not have the power to enact pay increases for any city employees, but it is expected to vote and forward a report outlining its recommendations to the City Council next week. The council has the final say over any pay scale changes.
