I am 100% in favor of workers' rights, and how workers are treated matters very much to me when I decide where to spend my money on vacation or household products or anything else. The fact that Walt Disney was listed in a book about the 100 best companies to work for was a strong influence in my decision to take a Disney vacation after I read it. I am not anti-union for the sake of being anti-union because I think that unions have functioned as a means of keeping management honest so that they don't do things like subtract hours from time records to avoid paying for those hours and other sneaky things like that, which certain companies are so notorious for doing that some supervisors have admitted on video to doing these things.
However, proceed with extreme caution if you should decide to join a union. Some union organizers don't care about their members but only their membership. If you choose to join a union, please attend the meetings and watch over how they spend your dues. I am not speaking against that union, and I am not management at Disneyland or Disney World. I have just seen a lot of what the world can do, especially to people as young and idealistic as many of you. It is okay to let someone get you hook and line but never sinker.
