Due to unexpectedly high turnout, announcement of results of the WGA’s strike authorization vote has been delayed for several hours.

The WGA West said Friday it’s received the largest voting turnout in the history of the Guild with nearly 5,000 ballots cast -more than half the WGA West members. The guild also disclosed that nearly 1,000 ballots were also cast by WGA East, which has about 4,000 members.

An announcement had been expected for about 2 p.m. PDT. But the guild said that because of the unprecedented turnout, it now expects to have a result late this afternoon.

The WGA could go on strike as early as Nov. 1.

The Guild’s returning to the bargaining table Monday — six days after the Alliance of Motion Picture & Television Producers withdrew its controversial residuals revamp — at WGA West headquarters in Hollywood. The session will be only the 11th day of face-to-face negotiations since the formal bargaining began in mid-July.
