Los Angeles (AP) The Screen Actors Guild will go it alone in contract negotiations with studios after the other major actors union rejected an invitation for joint talks.

In a letter monday to SAG, the American Federation of Television and radio artists said it would not revisit its decision to sever the guilds' longtime unified negotiations.

SAG'S talks with the Alliance OF Motion Picture & Television producers were set to begin Tuesday.

The letter from Kim Roberts Hedgpeth, National Executive Director of AFTRA, was addressed to Doug Allen, her counterpart at SAG. A copy was obtained by the Associated Press.
