Somebody out there must have evidence or recordings that depict the manner in which the company has deliberately chosen to get rid of their long-term employees through harassment, intimidation, and termination. There is no way that there is no such evidence in existence. We all know the direction that the company has taken and we all know that that direction comes from further up the food chain than market managers. Market managers have meetings with upper management and are given their marching orders at those meetings. Certainly somebody must have left their phone recording when they sat in on such a meeting and was then later terminated themselves for fabricated reasons. If you have such evidence, release it! This would be the kind of publicity any company dreads. Companies have the right to manage their human resources in any legal way they choose, but such a damning recording would immediately go viral and cause the kind of PR disaster that could be devastating. Especially to a retailer who depends on people to willingly spend their money in its stores. There are plenty of other far less repugnant places to spend it than at a Sam's or fricking Walmart.
If nobody exposes them, they are getting away with what they did to you, and the manner in which they did it. Think about that.
