What do you get when you cross a school of sharks with a tornado? A labor dispute. As a joke, that needs some fine-tuning, but it’s an apt description of the current status of Syfy’s Sharknado 3, which ran into a production snag this week when 30 to 40 crew members declared a work stoppage. Deadline reports the crew members are seeking a labor contract with representation under the International Alliance of Theatrical Stage Employees, a move that would secure them health and pension benefits. The crew on the second installment of Syfy’s schlock sensation had such an IATSE contract, but the latest Sharknado was hit by a whirling column of non-union workers.
