NEW YORK (AP) -- CBS News writers have authorized their union leaders to call a national strike.
The Writers Guild of America says 81 percent of the 300 writers who participated in a vote held last Thursday gave WGA negotiators the power to call a work stoppage.
About 500 CBS News television and radio writers -- who work in New York, Los Angeles, Washington and Chicago -- have been working under an expired contract since April of 2005.
CBS News and the WGA have not been at the negotiating table since January after the union rejected what CBS at the time called its final offer in November 2006.
Hollywood drama and comedy writers, who are also represented by the WGA, are entering the third week of an unrelated industry strike.
