The Employee Free Choice Act, also commonly referred to as "card-check" or "majority sign-up" legislation, was reintroduced in the House and Senate on March 10, 2010. The bill, which would allow employees to unionize by signing petition cards rather than only by secret ballot, has been the subject of a huge battle between organized labor and business interest groups. The AAUP strongly supports the bill and is working with other groups to support passage of the legislation.
