MINNEAPOLIS — Unionized transit workers in the Twin Cities metro have rejected a final contract offer and authorized a strike during Super Bowl festivities in February.

The Amalgamated Transit Union Local 1005 represents about 2,500 bus drivers, light trail operators and other Metro Transit workers. Members voted Sunday and Monday to reject the Metropolitan Council’s last contract offer by a 93 percent margin.

The union said changes to work rules, outsourcing and security for bus drivers are the main stumbling blocks to an agreement. The Met Council said it’s confident a deal can be reached before the Super Bowl.
