Representatives of Making Change at Wal-Mart, a grassroots effort supported by national labor unions, indicated that 200 Wal-Mart employees would hold a protest outside company headquarters in Bentonville, Arkansas, during the retailer’s annual meeting.
Additional protests could hit Wal-Mart stores on the Friday after Thanksgiving, potentially damaging holiday sales.
Investors appeared unconcerned by the protests. Wal-Mart shares rose more than 3% in Wednesday mid-day trading.
The employees who failed to appear at work this week were on strike, Making Change at Wal-Mart said. Last week, 63 store workers in Los Angeles missed work.
Protesting employees say they want higher pay and better working conditions.
Wal-Mart employs 1.4 million workers at its 4,000 stores in the U.S. The company dismissed the action as a stunt meant to garner media attention and accused unions of using its workers to advance their own political goals.
