I know from second hand experience that, although WalMart certainly isn't the greatest employer ever, it's nothing like what it's often portrayed as in union propaganda. I may not have a 'global' perspective, but I certainly do have a 'local' one. From where I've been standing, your worldview makes no sense.
And I know from
first hand experience that while Wal-Mart is
decidedly anti-union, it's a very good employer. Reasonable pay, very nice benefits. And no other breakroom I've ever been in has had rotisserie chicken up for grabs in it - even occasionally.
