The world’s largest retailer says the union’s protests included “flash mobs” inside its outlets, as well as “picketing, blocking entrances, staging group confrontations with members of management and even conducting flash mobs inside our stores”.

“This action does not seek to prevent defendants from engaging in peaceful labor-related activity outside of Walmart’s stores as permitted under California law. Rather, it seeks only to stop Defendants’ ongoing practice of unlawfully trespassing inside Walmart’s stores to engage in disruptive and harassing conduct, none of which is protected under California law,” the lawsuit, seen by just-food, reads.

The action lists protests at Wal-Mart stores in the state between August and November.

“Their illegal trespassing has made some of our customers uncomfortable, has disrupted our associates’ work and, in many cases, we’ve had to call police to get them to leave. The lawsuit filed against the UFCW and its agents is to help protect our customers and associates from further disruptions associated with their continued, illegal trespassing. Their unlawful actions are disrespectful to both our associates and our customers and have to stop,” the retailer told just-food.
