Von's is owned by Safeway. Dominick's, in the Chicago area, is also owned by Safeway. They tried this crap in Chicago but, Jewel employees had already signed their contract so, no lockout. Isn't it collusion when different employers band together to set prices, work environment, and pay scale?
Here's a link to a Safeway employees site. Check it out if you have the time.
