A former Walmart employee was handcuffed Wednesday when he visited his old store to talk to workers about next week’s “Black Friday” strike. Alex Rivera, who was fired in September, told The Nation that Walmart management intentionally misled Orlando police, leading them to detain him for twenty minutes in the store. The incident was denounced by the union-backed workers’ group OUR Walmart, which alleges that Walmart has been breaking the law to keep its workers in line.
