OAKLAND, Calif. (AP) - The mayor of Oakland says the city will file a labor complaint if about 3,000 workers walk off the job Tuesday.
Mayor Libby Schaaf says a strike called by labor unions is unlawful because the two sides have not reached an impasse.
Union leaders say workers in senior centers, libraries, City Hall and other city-run departments will strike starting at 7 a.m.
Police and fire services will not be affected.
Members of Service Employees International Union Local 1021 have worked without a contract since June 30. The union says the city underpays and relies too much on temporary help.
Members of an engineers union will also join the strike.
Oakland has a population of more than 400,000.
