“Sharknado 3” has just been hit by another kind of storm.

The third installment of Syfy’s camp-tastic disaster movie series shut down production on Tuesday morning, after the film’s crew voted to strike for an IATSE union contract, the Motion Picture Editors Guild said on Twitter.

The guild tweeted that, at 9 a.m. PT, workers were picketing at the film’s production office in Burbank, noting, “If you receive a call to replace striking workers on #Sharknado3, call your local union immediately!”

The organization added, “The Editors Guild instructs members & prospective members not to render services on this production during the strike.”

The striking workers, 30 to 40 in number, are asking for benefits, along with standardized wages and working conditions. The previous production “Sharknado 2:,” had been unionized.

The International Alliance of Theatrical Stage Employees, Moving Picture Technicians, Artists and Allied Crafts of the United States (IATSE) also shared news of the strike, which is IATSE-wide.
