I have one near me. They do this, I am going to the other supermarket in town, no questions asked.
I am not paying my money for union crap.
One reason Pittsburgh has always been a relatively expensive place to buy groceries is that Giant Eagle had pretty much of a monopoly until recently. This is because union nonsense managed to drive all of the other chains out of town. After Kroger left in ‘85 they had the market pretty much to themselves until the fairly recent arrivals of Super Walmart, Aldi, etc.
I can’t imagine Stop & Shop strikers will enjoy nearly the popular support that Market Basket personnel did when they walked several years ago.
