The Employee Free Choice Act is the name for several legislative bills on US labor law (H.R. 3619, H.R. 1696, H.R. 800, H.R. 1409, H.R. 5000, S. 1925, S. 842, S. 1041, S. 560.) which have been proposed and sometimes introduced into one or both chambers of the U.S. Congress.

The bill's purpose, as taken from the 2009 version, was to:

amend the National Labor Relations Act to establish an efficient system to enable employees to form, join, or assist labor organizations [unions], to provide for mandatory injunctions for unfair labor practices during organizing efforts, and for other purposes.

The act would have, first, allowed a union to be certified as the official union to bargain with an employer if union officials collect signatures of a majority of workers. The bill would have removed the present right of the employer to demand an additional, separate ballot when more than half of employees have already given their signature supporting the union. Second, the bill would have required employers and unions to enter binding arbitration to produce a collective agreement at least 120 days after a union is recognized. Third, the bill would have increased penalties on employers who discriminate against workers for union involvement.
