COLUMBIA — The South Carolina House has advanced a measure that would exempt businesses from a proposed federal rule that they notify workers of their rights to unionize.

The House approved the bill today on a 76-26 vote. It requires another perfunctory vote before heading to the Senate.

It’s the latest show of Republican lawmakers’ disdain for unions in a state that markets itself as anti-union.

Republican Rep. Alan Clemmons of Myrtle Beach says it sends a message to the National Labor Relations Board.

The board’s proposal would require businesses to post the 1935 federal law that guarantees employees’ right to collectively bargain, distribute union literature and engage in union activities without punishment. The agency is reviewing comments it received during the public comment period. No date is set for a decision.
