Well,actually,they ARE a union store. It's not a question of shopping at a non-union store, it's a question of the new contract that they haven't been able to vote on (because of the union)and that they evidently don't want.
So, of course, if the employees are against the new contract (and this IS what's all about), I guess, we should assume that we and their union know more than they do about what's good for them, since they come from lower economic strata, and don't have the smarts or education that we and their union has.
Your so right, why even bother talking to the employees to see what THEY want.
