Screen Actors Guild
Screen Actors Guild - until 2012, when it merged with the American Federation of Television and Radio Artists to become SAG-AFTRA
A union for actors. Most of its members were also members of AFTRA, the American Federation of Television and Radio Artists - which is one reason why the two unions merged.
Parodied in the film Team America: World Police with the Film Actors Guild (see Fun with Acronyms). See also: Unions in Hollywood.
