Why Unions Suck: Part 820457

From Philly.com:
Screwdriver vs. power tool. That's what led to Thursday's roughly 12-hour strike at the Convention Center, which ended with a one-year extension of the customer-satisfaction agreement between the Pennsylvania Convention Center Authority and the city's unions, and a one-year extension of collective bargaining agreements....
But the screwdriver-vs.-power tool issue, and all that it stands for, blew up three days of smooth negotiations between union and Convention Center officials about 10:30 p.m. Wednesday, say those involved in the talks. The current provisions, detailed in the customer-service agreement, let exhibitors set up booths as long as they are no larger than 300 square feet and as long as they do not use power tools. Most booths are 10 feet by 10 feet or 10 by 20. Management wanted to let exhibitors use power tools to assemble booths regardless of size.

I honestly don't know what exhibitors can or cannot do in Las Vegas, but seriously, if I am an exhibitor, why would I want to hire a union person just so they can use power tools to set up an exhibit?
This is just a bunch of union thugs trying to extort money from exhibitors.
