I think that is a sweeping generalisation R1.
I work for a multi-national company who tries long and hard to be as efficient and cost-effective as possible - no problem, that's how businesses thrive.
The problem is, management culture regards employees as simply expendable and moveable units to be shifted around the business as and when it suits - with no regard for individual circumstances, skills, and so on.
Someone such as myself was advised that i would love into a job utterly unsuitable for me, which would have resulted in serious stress, and possible psychiatric hospitalisation.
As an individual, my concerns would have been ignored by the company.
As a Union Member, i had access to support, correct proceedures, and an appeals process which meant that this move was stopped, and i have been re-located to another job, which benefits not only myself, but the company, so everybody wins.
Without the Union, I would have been moved, and had to leave my job - a loss to both myself and the company.
Unions exist to protect the rights of employees - don't imagine that just because this is 2010 that all cliches apply.
