Walmart sued over temp workers hours NEW YORK Walmart (WMT) is being slapped with a lawsuit that claims that the largest retailer and its staffing agencies broke federal minimum wage and overtime laws by requiring temporary workers to appear early for work, stay late to complete work and work through lunches and breaks without compensation. According to the proposed class action suit that was filed Monday in the U.S. District Court of Ilinois' Eastern Division, Labor Ready and QPS, two of the staffing agencies that the discounter used in the Chicago area, failed to provide workers assigned to the Walmart stores with required employment information. The suit also claims that Walmart itself failed to keep accurate records of workers' time. Walmart and the temp agencies did not immediately respond to requests for comment.
