"It makes no sense to me that union creating more expensive labor would increase the costs of non-union labor, except insofar as they reduce the size of the non-union labor pool." I don't have a link. This is all anecdotal. I could be completely wrong but I don't think I'm far off. Lowering the pool of non-union workers is one thing, but also competing to keep those workers from joining a union. Companies generally don't want to be unionized. Not only do they need to compete to keep the worker from leaving but they also need to pay enough to keep the workers happy enough to not unionize their shop. I'm from WV which is basically owned by the coal mines. Each time one of those non-union mines go to vote if they will go union the miners I know tell me the company starts giving out bonuses and things like Harleys to sway them to vote non-union. Even so things that were created or backed by unions have now become laws and directly benefit non-union workers. Like the 40 hour work week. The end of child labor. Employer health benefits. FMLA.
