Correct rejecting the companies "best and final" contract is basically par for the course in union negotiations. The company is banking on being able to outlast the strike to get a better deal than the union would otherwise agree to or betting on the government coming in an kneecapping the union and forcing the workers to accept a deal like happened with the ATC and train operator unions when they struck (striked? struck doesn't sound right in the context of a union strike for some reason...).
