Stores that abide by union-negotiated contracts but whose employees aren't enrolled in a union (such as Costco stores in CT);
Stores which do not have a union but do not actively prevent workers from organizing (i.e. Trader Joes, some IGA / indie grocery stores);
Stores which consistently apply anti-union pressure to prevent workers from organizing under a union (Whole Foods, Wal-Mart);
Stores which are being picketed by its employees after failed contract negotiations; and
Stores where the management has locked-out workers who wish to work despite the absence of a contract.
I'm curious, if a strike goes down at Stop and Shop this week, the kinds of store you'd be comfortable shopping at. A poll and discussion over the fold - though the polls are secret ballot, so vote based on your own comfort level and situation (distance to nearest other store, etc).
