The Employee Free Choice Act, also known as the card-check bill, is once again back in Congress. The U.S. House and Senate both have bills to reintroduce the bill which would allow workers to form unions by signing cards and replace traditional secret-ballot elections.

The bill did actually pass the House in 2007, but the Senate rejected the messure. As part of the full provision, the bill would also allow a binding arbitration process if a first contract is not finalized following union recognition.

The latest card-check bill re-entered Congress this week, introduced by Rep. George Miller (D-Calif.) and in the Senate by Sen. Tom Harkin (D-Iowa).

Two weeks earlier, House and Senate Republicans introduced the Secret Ballot Protection Act to counter the card-check option. Given the two opposing options, the debate will have to unfold.
