The Portland City Council on Monday approved a new contract with its largest union that will increase wages $1.1 million over the next three years. The agreement with the roughly 500 workers in the City Employee Benefits Association, which represents most permanent employees except for firefighters and police officers, provides annual increases of 2 percent. The contract with the American Federation of State, County and Municipal Employees Local 1373 will expire on June 30, 2019. The council previously granted significant raises to other employees who report directly to the council. City Clerk Katherine Jones received a 17 percent raise, increasing her annual salary by nearly $14,000 to $92,960.
