The South Boston-based Iron Workers Local 7 union has endorsed Josh Kraft for Mayor, according to his campaign.

“Josh shares our members’ values,” said Vincent Coyle, Jr., business manager at Local 7. “He understands the importance of their work, and we are confident he will protect the working families of today and tomorrow.”

For his part, Kraft, said: “Having seen their work for three-plus decades in Boston’s non-profit sector, I know the Iron Workers’ reputation. Their members get jobs done on time and on budget. And frankly, we could use a little more of that in City Hall these days.”

Mayor Wu has been endorsed by several key city unions, including the Boston Police Patrolman’s Association, SEIU, AFSCME Council 93, and Laborers Local 223.
