This is an unofficial list based on my research – the best way to know if your location is unionized is to ask someone there.
I will update this list as I find out more.
There are at least 56 unionized locations, most of which are in California. There are several (16) in New York, New Jersey, Maryland and Virginia that are unionized as well. The latest one to unionize was a location in Norfolk, Virginia.
Last week, after voting to authorize a strike, unionized Costco workers organized a practice picket line at Hayward, California and Sumner, Washington (a Costco Distribution Center). They also did a practice picket on Long Island and Sacrament, CA.
