Unions have their place at times, but much of the time they abuse their role to the point where
(1) workers are less productive and
(2) of sufficiently poor quality and
(3) wages are uncompetitively high enough
to render a company uncompetitive in a business environment. In short, an aggressive union can run a company right out of business through poor product and stupid high overhead. This is anything but behaving in the best interests of the workers.
At other times, they simply form a useless parasitic form of wage tax between workers and their paychecks.
Would you have bought a Chevy Cavalier knowing you're paying for a $6000 car with $7000 worth of worker benefits and pension obligations? Knowing that the car you bought for $13,999 is worth $7000 in eighteen months because that's it's real value? That's why GM tanked. You survive as a company because you can build a great product at a decent profit and attract the best talent.
Want to see how good your union is? Ask the union to take a dues cut when your industry tanks in order to keep the workers working and the company competitive. I have never heard of a union doing such a thing.
This is table 9.1 from Cukier and Sidel's "The Global Gun Epidemic", 2005. Don't forget that Canada's Labour Unions are official members of the Coalition for Gun Control. CAW and the CLC actively campaigned against Bill C-391. Your union very likely wants to take ALL your firearms away from you, regardless of where they are made.
