Workers at a Southern California warehouse began a strike on Wednesday over working conditions. The strike is part of a series of actions aimed against Walmart, who the warehouse supplies. Workers both in the warehouses that supply the chain, as well as in the store, are threatening to strike on Black Friday, potentially disrupting the biggest shopping day of the year. The workers at the warehouse say that they are promised more hours than they get, and that they deserve better working conditions. Walmart says that they are investigating the claims at the warehouse.
