Today, for the first time in Wal-Mart’s 50-year history, workers at multiple stores are out on strike. Minutes ago, dozens of workers at Southern California stores launched a one-day work stoppage in protest of alleged retaliation against their attempts to organize. In a few hours, they’ll join supporters for a mass rally outside a Pico Rivera, Calif., store. This is the latest – and most dramatic – of the recent escalations in the decades-long struggle between organized labor and the largest private employer in the world.

“I’m excited, I’m nervous, I’m scared…” Pico Rivera Wal-Mart employee Evelin Cruz told Salon yesterday about her decision to join today’s strike. “But I think the time has come, so they take notice that these associates are tired of all the issues in the stores, all the management retaliating against you.” Rivera, a department manager, said her store is chronically understaffed: “They expect the work to be done, without having the people to do the job.”
