Former Massachusetts Gov.

The Workplace Fairness Institute announced that Romney will appear at a forum in opposition to the Employee Free Choice Act on Thursday in Arlington, Va.

Romney has opposed EFCA for quite some time, according to spokesman Eric Fehrnstrom. In 2006, Romney vetoed a card check bill for Massachusetts public employees when he was governor.

"He thinks it's bad for workers, bad for management and bad for the economy," Fehrnstrom said.

Romney also discussed the issue in a Washington Times op-ed earlier this year and in his speech at the Conservative Political Action Conference in February.

Romney has carefully weighed into the public dialogue on several issues recently. In addition to his statement on Sotomayor, he blogged on President Obama and former Vice President Dick Cheney's national security speeches last week.
