OAKLAND, Calif. (AP) A Bay Area Rapid Transit labor union has overwhelmingly ratified a contract agreement after a bitter dispute prompted two San Francisco area strikes.

Officials of Service Employees International Union Local 1021 announced late Friday night that members approved a four-year contract with BART that covers workers responsible for the repair, maintenance and cleaning of the BART system.

The union says 88 percent of Friday's vote was in favor of a contract that provides for reasonable wage increases and a compromise on pension and health care costs. The agreement also calls for significant safety improvements at the transit agency.

The second BART union, the Amalgamated Transit Union Local 1555, also voted on the contract Friday, but there was no immediate word on the outcome.
