HARTFORD, Conn. (AP) _ Connecticut lawmakers are sending a bill to Gov. Dannel P. Malloy that requires the State Board of Education to encourage local schools to teach students about labor history.

The House of Representatives on Monday passed the legislation, 84 to 51. The bill previously cleared the Senate.

Under the proposal, the State Board of Education must make resources available to schools about the history of organized labor, the collective bargaining process and legal protections in the workplace.

Similar bills failed in previous sessions. This year’s bill also requires the history and economics of free-market capitalism to be included.

The curriculum is voluntary for schools.

Unions and their allies have pushed for labor history to be part of social studies curriculum, hoping a new generation of students will become educated union members.
