Left me to fight for my own raises (which I prefer but not if I'm forced to pay for representation with dues).

My father had sorta the same problem...he belonged to a union, but it was the rank and file who fought for the benefits (a really good pension plan and excellent health insurance). The union was lousy at negotiating contracts. If he had his druthers, my Dad would never have had a union. I have never worked under a union, and I've done very well without it.
The majority of people that benefit most under a union are those inclined to be lazy, those that are not qualified as it's very difficult to fire them. It's the ideal position for them.
Those that are neither are forced to carry their weight as a result. My union was okay in overall negotiating but supporting workers individually? Difficult to get their attention. The bigger problem was that they bled the company dry, a company with questionable leadership anyway, between the two factors the workers suffered with lost hours and lowered benefits because of the lost hours.
The place I'm with now has competitive pension and insurance, direct access to the boss to negotiate terms, and is able to undercut the competition in prices. If you do not do the job, you are fired. I prefer this environment. In its way it's far more secure than a store slowly dying due to the grip of a union.
