The unions only interest in Walmart is the great untapped source of income from collecting union dues from it's employees should they be able to unionize. Aside from that, the union could give a rat's ass about Walmart employees.
Has anyone noticed the absence of criticism for Home Depot, Lowes. Sears, K Mart, Target, and many other dept stores and discounters? These are generally non-union as well.
This give a strong indication that this is not a legitimate issue, but a CAUSE put forth by union activists.
IN this latest attack on Walmart, it has been discovered that is it not mainly Walmart employees staging these protests, it is people shipped in bu instructed to travel to protests by unions. Simply to stir up trouble.
My take is the more unions push this, the more blow back they receive from an unsympathetic public.
