Thousands of Fred Meyer workers in the Portland area plan to walk off the job early Wednesday, striking over alleged breaches of labor relations laws and amid contentious contract negotiations.

The United Food and Commercial Workers Local 555, which represents roughly 4,500 Fred Meyer workers across the Portland area, told The Oregonian/OregonLive on Tuesday that the strike would begin at 6 a.m. Wednesday and continue nearly a week, until 8 a.m. next Tuesday.
