Since the union is organized labor, it is they who are working for the money.
Think about the NFL lockout. The players are all organized together to stand up for their own rights since it is they who work to generate the money that the NFL produces. The money is not coming from no where, the players are the ones who generate it.
I guess you buy into the story that they are outrageously compensated.
According to Keefe, comparing private and public employees with the same educational level, experience and work schedule shows private employees make 11 percent more in wages and 5 percent more in total compensation than public workers. Using the latest federal data, Keefe said the average total compensation for workers in the private sector with bachelor’s degrees is $89,041 compared with $56,641 for public workers.
For workers with professional degrees — lawyers, say, or doctors — the gap is more dramatic: $175,141 in the private sector, $79,330 in the public.
Public workers are more educated than private — 57 percent have college degrees and higher, compared with 44 percent.

However, among workers with minimal education backgrounds, public workers make more then private workers. Throw in a diploma, and they make about the same.
Now, for Wisconsin workers:
However, the data indicates that state and local government employees in Wisconsin are not overpaid. Comparisons controlling for education, experience, organizational size, gender, race, ethnicity, citizenship, and disability reveal that employees of both state and local governments in Wisconsin earn less than comparable private sector employees. On an annual basis, full-time state and local government employees in Wisconsin are under compensated by 8.2% compared with otherwise similar private sector workers. http://epi.3cdn.net/9e237c56096a8e4904_rkm6b9hn1.pdf
But the next time you get your bank statement and see all those fees, guess who is paying for the multi-multi-million dollar compensation package of the Bank CEO.
But lets say you really dislike unions. Well. private companies that are non-union pay wages to keep unions out, so you lose unions and the company doesn't have much of an incentive to keep your pay and benefits up.
