Walmart, like many large corporations, frowns upon unions. All employees must sign away their rights to join a union. What does this mean? Should you be mistreated, poorly paid, and ignored, who do you turn to? Walmart has been slammed with numerous lawsuits. Just to name a few: gender discrimination, sexual orientation discrimination, and racial discrimination. What Walmart, and many large corporations, know is that should these unhappy employees become organized (i.e. unionize), they become a force to be reckoned with. They would then have to increase wages and engage in fair practices and who wants that, right? Walmart is notorious for their union busting tactics. If they catch wind of anything they will exert pressure on individuals to prevent them from organizing.
What kind of pressure? It all begins when the Labor Relations teams come into the stores, holding meetings where they berate unions, presenting only one side of the issue. Team members leave scared and confused about unions, only having heard one opinion. Union activists are banned from stores so they never do get to hear the benefits of unionizing.
Other underhanded tactics include management eavesdropping on employees, threatening employees with pay cuts, benefit loss, or even job loss should they organize. According to Human Rights Watch,
Let's go one step further. Business is business. While Walmart has made steps as of late to remedy some of their issues, they will not willingly become as ethical as you or I would like. The only way they will do that is if they have to, i.e. laws. There are many movements active right now regarding changing labor laws so that corporations cannot do all the things Walmart is accused of. While I believe in the goodness of people, business is all about the bottom line so we shouldn't expect Walmart (or any other business) to change because they want to 'be good'; we have to force change or it won't happen.
