Warner Bros. could slash up to 1,000 jobs after Friday, citing effects from the writers’ strike, THR reports. While the studio isn’t saying that it will cut that many jobs; companies are required to issue a notice of impending layoffs related to a strike under rules from the U.S. Department of Labor’s Worker Adjustment and Retraining Notifications, which has the appropriate acronym WARN.

WB’s WARN were initially issued to employees on Nov. 12, with recipients subject to layoff 60 days after posting of the notifications. Tuesday was the 65th day of the Writers Guild of America’s strike against the studios over the division of media company’s internet earnings. So far, while a number of studios have looked to cut costs in the wake of the strike, none have so far eliminated any jobs. If WB does initiate layoffs, other studios are expected to quickly follow suit.
