It's not that the state writes a law that gives the unions leverage. They write laws to /take away/ leverage from a union. There's nothing to guarantee any kind of break from work for an employee, unless it's a law or it's part of the agreement between the employer and the employee. So if the state makes it a law, that is one less benefit a union can negotiate for their members.
