(Reuters) – Telecommunications operator AT&T (NYSE:) on Friday ratified contracts with the Communications Workers of America in the Southeast and West, which employs about 23,000 workers in eleven states.

The union said workers in the West would receive wage increases of at least 15% over the course of the up-to-date four-year collective agreement, while workers in the Southeast would receive more than 19% pay rises over the course of the up-to-date five-year agreement.

In August, more than 17,000 company employees – including technicians and customer service representatives and others who install, maintain and operate AT&T’s wired telecommunications network for homes and businesses – went on strike in August to protest unfair labor practices.

Wire technicians and utility operations specialists in the Southeast will receive an additional 3% pay rise as part of the Infrastructure Bill, the union said in a statement.

In September, the union informed the Federal Service for Mediation and Conciliation that it would no longer participate in mediation because the operator was using it as “another delaying tactic”.
