If the union did in fact do this they would be breaking the law-no doubt. However, isn't it ironic that the "Right to Work Legal Defense Foundation" is going to bat for this person against his union when in fact, as an organization they would support the employer in a heartbeat for firing him from his job for no reason at all? It's true and it's called "Employment At Will". It's what you are stuck with if you don't have a union representing you at your place of employment. The "Right to Work" groups are in fact fronts for big business and their goals are to keep wages and benefits as low as possible while not allowing workers any rights on the job. Thus, the unions stand in their way as the unions aim to improve wages and benefits while giving workers a voice at work. They jump at every chance to go after the unions whether it is warranted or not.
