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.
