Legal Question in Business Law in California

One thing I don't do for a living is bust unions. There are plenty of high-priced lawyers out there who do. If I knew how, I sure wouldn't post the information to a public forum.

The record for a strike with the business being run in the meanwhile by non-union replacement workers (a/k/a scabs) was probably the strike against the Florida East Coast Railway, which began in 1963 and ended when the FEC was sold to a new owner, not governed by the old labor contract, in 1977. So, that one lasted 14 years and was resolved in a way that probably won't work in the grocery-chain milieu, although your question suggests that they might try. Also, grocery stores compete in a different market than medium-sized railroads, and depend upon union members for their sales volume. I predict a settlement in less than a year, maybe a lot less.
