Mayor Michelle Wu indicated she may veto the pay raises that the City Council last week unanimously approved for themselves and the mayor.

Under the proposal, starting after the 2023 council election, councillors would make $125,000, up from the current $103,500, while the mayor will get a bump up to $250,000 from the current $207,000 after the 2025 election.

The council also approved increases for the police and fire commissioners and other top appointed officials, with those raises going into effect immediately.

Appearing on GBH’s “Boston Public Radio” on Tuesday, Wu said the proposal she first proposed to the 13-member council had an 11 percent increase for elected officials. The council is seeking a 20 percent increase, which is “too high,” Wu said.

The pay raises would come as city workers, including first responders, are working under expired contracts. “The timing of it is concerning to me, and the scale of it,” she said of the council’s proposal, while acknowledging that overriding a mayoral veto takes nine votes.

For their part, councillors said they were only doing what they must to ensure that Boston stays in line with “peer cities” like Washington D.C., Seattle, and Minneapolis. Currently, Washington and Seattle councillors make more than their Boston counterparts while Minneapolis legislators make the same. Councillor Ruthzee Louijeune used the occasion to note that housing is so much cheaper in Minneapolis than in Boston.

Council President Ed Flynn acknowledged that rank-and-file city employees mostly make less than councilors, but added, “they, too, deserve a pay raise. We work best when we work together.”

Among those supporting the raises at a hearing on Monday: Former Councilor Tito Jackson, who, in an earlier debate about council wages, said he almost lost his house to foreclosure when he ran for the District 7 seat the first time.
