A National Labor Relations Board judge says Wal-Mart Stores Inc. unlawfully disciplined workers who staged protests in May and June of 2013 and ordered the retailer to reinstate 16 former employees, as well as give them back pay. The decision, posted on the labor board’s website late Thursday, Jan. 21, 2016, arrived one day after the nation’s largest private employer said it was giving raises to most of its hourly employees.
