http://www.theonion.com/articles/In my 27 years as a union-certified plumber, I've heard every negative stereotype you could possibly imagine: Union plumbers charge too much; union plumbers are lazy; union plumbers take way too long on jobs. Now, I'm not going to stand here and say there aren't a few bad eggs out there. There always are. But the fact is, when you hire a union plumber, you're getting quality workmanship from a thorough, highly trained professional whom you will never walk in on giving the high hard one to your missus if you come home early from work.
No matter how bad she's begging for it. That's the UA Plumbers guarantee.
I can't tell you how many horror stories I've heard from clients who tried to save a buck and went with some cut-rate scab plumber only to discover his wife getting plowed six ways from Sunday and, on top of it, find out later that the seal around his new tub leaks like a friggin' sieve.
Wouldn't happen with a union wrench. Any customer who hires myself or one of my colleagues can rest assured his bathtub will be snug as a bug and his wife will be left in the same condition as the plumber found her: horny as a goddamn polecat in heat and ready to get the holy bejeezus pounded out of her at the drop of a hat, but totally unfucked.
That's peace of mind you just can't find with a nonunion contract.
