A state legislative panel in Ohio plans to hear testimony on a proposal that would bar private employers from requiring workers to join or pay dues to a labor organization.
Such right-to-work laws have been enacted in 25 states. Ohio's bill is slated to get its first hearing Tuesday afternoon before the House Commerce and Labor Committee.
Right-to-work proposals have not gained traction in the Ohio Legislature, particularly after the state's voters overwhelmingly rejected collective bargaining limits for public employees in 2011.
Republican Gov. John Kasich has said such legislation is not his priority.
The supporters of right-to-work legislation have argued that it would help the state attract more businesses and make it competitive. Opponents claim it would weaken unions and could lead to lower wages.
