The NLRB withheld the announcement until mid-January in hopes the parties could settle their differences.
The complaint alleges that Minnesota supervisors “unlawfully threatened, disciplined, and/or terminated employees for having engaged in legally protected strikes and protests.”
The consolidated complaint names more than 60 Walmart supervisors and one corporate officer. An NLRB statement said other charges are still under investigation.
The complaint claims that 60 employees were disciplined for their actions, including 19 who were discharged. It cited two television broadcasts in California and Texas that threatened employees with reprisals if they took part in protests or strikes.
