The Michigan House today (Tue) gave final approval to a measure making Michigan a so-called "right to work" state, which prohibits requirements that workers pay a fee that would go to a union as a condition of employment.  The first bill in the package, which affects public employees, was approved on a 58-to-51 vote.  The second, which affects private sector employees, was approved on a 58-to-52 vote.  The votes came as thousands of demonstrators flooded the Capitol building, and the east lawn of the Capitol.  Labor unions oppose the bills, saying it's just designed to hurt unions.  The Governor, who promises to sign the legislation into law, says the measure will help Michigan's economy, but not at the expense of labor unions.
