Union in the Deep South

Hello all!

I live in the Deep South where unionizing or the discussion of unionizing is frequently frowned upon (I know of the local plumbers in pipe fitters union, nursing, and maybe a teachers union), at least in my experience it seems to be an area unfriendly to the encouragement of unionizing.

I know Albertson’s and the other stores within the company have a union, but does this include every store in the country? Or are only some of the stores participating? How would I go about finding out if my store participates? Because of the attitudes towards unionizing here, I know very very little about the subject or how to go about finding out the information.
