My brother has worked as a stocker for King Kullen in New York for 20 years and is a union worker.

In the Seattle area where the poster is from, pretty much all the grocery stores are unionized. Workers at big stores like Safeway, Fred Meyer, QFC, and Albertsons, and local stores PCC, Uwajimaya are represented by UFCW3000. https://ufcw3000.org/shop-union

Additionally, Teamsters 174 organizes a lot of the grocery freight workers. https://teamsters174.net/warehouse-and-grocery/
