Whole Foods, from most accounts, provides generous healthcare and is a comparatively good retail/service job - so this isn't a boycott about workers' rights in the traditional sense.  Instead, it's a pointed rebuke of the idea that we lack the right to healthcare. The more we can raise our voices that all of us have a right to a home, a good job, adequate healthcare, sustainable wages, the more we can get beyond incremental changes in our tattered safety net.
