Here's an interesting question:
Walmart is trying to bust into the Chicago market with a 2nd store, thus dragging down the wages and working conditions of employees at competitor companies, many of whom are represented by the good people at UFCW.
So, in order for them to grease the way so to speak, this monster corporation has flooded the airwaves with testimonials supposedly from employees of how awesome Walmart as an employer is.
I've heard the same commercial over and over again on the CBS affiliate WBBM the whole week.
