The Intl. Alliance of Theatrical Stage Employees will strike for a second weekend against the Pac 12 Network.

The below-the-line union plans to set up strike lines Saturday outside basketball games at UCLA’s Pauley Pavilion and the University of Southern California’s Galen Center in Los Angeles, Arizona State University in Tempe, University of Washington in Seattle; and at UC Berkeley.

IATSE has labeled the network an “unfair” employer and picketed a quintet of games last Saturday in support of unionizing broadcast technicians on the recently launched sports network. IATSE has said the strike is an attempt to establish standard wages and benefits for daily hire technical employees of the network working on live sporting events.

The Pac-12 Network has indicated it will continue to use non-union labor as part of a statement that it “respects the right for workers to decide on union representation.” The fledgling network has contracts with Time Warner Cable, Comcast, Dish Network and Bright House Networks.

The union has said that since the network went on air in September, it has employed technicians represented by IATSE at venues of the 10 institutions in its jurisdiction while also crewing many events in those markets using non-union labor, or a combination of non-union and covered labor side by side on the same job.
