Unions have come to rely on the public sector because government employees are easier to organize, and managers less resistent. Who's going to put up a fight over an organizing campaign with a politically active union when taxpayers are paying the bill? If the union wants nicer benefits, it's easy to cave in, tax dollars and budgets be damned. It's good for campaign coffers.. . .
Public-sector unions rallying in Madison aren't even taking a hit for their political activism, given that their protest is made possible by paid sick days, negotiated for them by their collective bargaining units who, it must be said, donate to the very people with whom they negotiate.
If public sector unions want the right to collectively bargain over who gets my money - fine, as long as I get to sit a the table, too. Politicians, especially those designated "D" have, not a conflict of interest, but an interest all-but-indistinguishable from the union bosses on the other side of the table. Enough.
