In preparation of interruptions to one of its busiest shopping weekends of the year, Walmart, the largest employer in the country with 4,000 U.S. locations, had requested last Friday that the National Labor Relations Board issue an injunction against planned protests outside Walmart stores during Black Friday, but the NLRB Office of General Counsel said it needed more time to conduct an investigation and issue a decision.
Walmart does not recognize an official workers' union and alleges that the UFCW union is organizing illegal picketing at its stores.
Labor advocates critical of Walmart say it does not pay workers enough and many part-time workers are unable to work more hours and earn additional income.
Colby Harris, a full-time Walmart employee in Lancaster, Texas, for the last three years, said workers were protesting by walking off their shifts.
Harris, 22, said he left his shift of 5 a.m. to 2 p.m. Friday along with a handful of associates. He plans to return to work for his next shift on Monday at 5 a.m.
"Nationwide workers are continuing to go on strike as we speak," he said.
