The Writers Guild of America had refused to grant a waiver to allow its members to work on the Golden Globes, the People's Choice Awards and the prestigious Academy Awards.
Rosenberg also weighed in on the late-night talks shows, which are back on the air. Some are working without writers after failing to strike deals with the writers guild.
Rosenberg stopped short of pressing actors to skip the picketed shows, like Jay Leno's "Tonight."
"We urge our members to appear on the two programs that have independent agreements with the WGA, `The Late Show with David Letterman' and `Late Late Show with Craig Ferguson,"' he said.
Actors who appear on other shows have to cross picket lines, he said.
That creates "the same situation that has led to the consensus among actors to skip the Golden Globes," Rosenberg said.
