The people behind Army Wives are worried another strike is coming, the second in more than a year.

The Screen Actor’s Guild, Hollywood’s largest union, asked its members on Saturday to approve a strike after talks with an alliance of movie studios failed due to disagreements over online and new media provisions. Though union officials have requested it, a strike is no guarantee. At least 75 percent of the organization’s 120,000 members must approve the move.

The second season of Army Wives wrapped production in October. A third season is set to begin shooting in January. Insiders, though, are afraid the production schedule will be postponed indefinitely if there’s a strike. Army Wives was already set back by a writers strike that ended only in February. That labor dispute gummed up the works for many TV shows, even forcing the Golden Globes to downsize. —John Stoehr
