I can think of two S&S stores in my area with much more competition than even a year or two ago. One has two non-union full service grocery stores directly across the street, visible from the S&S parking lot. Additionally a Costco, new Aldi and just renovated Super Target withing a half mile and a Super Center WalMart about 8-10 minutes away.
The store store where this rally was held practically shares a parking lot with a non-union competitor, a Super WalMart across she street and a Price Rite ~1.5 miles away.
I also forgot about the BJ’s that is literally 250ft behind the Stop & Shop where the union had their rally.
