Walmart mostly hires the unhireable and pays them what they are worth. It Walmart stores are unionized, these unhireable people will lose their jobs for incompetence.
The union fight at Walmart is not over the retail jobs, it is over the trucking and warehouse jobs. The unions could care less about the retail workers. They don’t really want them in their unions, except for the potential clout that the retail workers weld.
It was revealed this morning on Drudge that the protesters at LAX didn’t even know what they were protesting, that they were members of other unions and just showed up because they were told to. Many of the union members at LAX opposed the strike. My guess is that it is the same at Walmart.
