LANSING, Mich. – As the chants of angry protesters filled the Capitol, Michigan lawmakers gave final approval Tuesday to right-to-work legislation, dealing a devastating and once-unthinkable defeat to organized labor in a state that has been a cradle of the movement for generations.

The Republican-dominated House ignored Democrats’ pleas to delay the passage and instead approved two bills with the same ruthless efficiency that the Senate showed last week.

One measure dealt with private sector workers, the other with government employees.
