At present the opposite is true. There's a Simpsons episode that's especially pertinent, where Mr Burns was recalling his childhood (presumably in the 1930's) where workers had no rights at all, then he compared it to modern times where unions and strikes greatly altered the balance of power in favour of employees.
Australia went through an insane series of strikes in the 1970's and 80's, mostly from employees in the most lowly of jobs. There was a notorious group called the "Storeman and Packer's union" who seemed to go on strike every month over some petty quibble. There doesn't seem to be a wikipedia entry, however they're mentioned in this article on one time Federal Labour Party leader Simon Crean: http://en.wikipedia.org/wiki/Simon_Crean
The railways and busses, which at that time were 90% government operated, were renown for going on frequent strikes, particularly during school holidays because it drew more attention.
Ultimately the consequence of all these strikes was that it drove wages much higher, and improved workers conditions overall tenfold. However employers countered this by reducing the number of staff, or worse yet, by outsourcing to countries where wages were much lower. Austraia isn't a sweatshop, it runs sweatshops overseas, paying workers one third of what they pay here. Meanwhile people like me are stuck doing the work of three people, just to cover the costs of the high wages, which in turn go to pay all the high costs of living.
It means high unemployment, and extreme stress for those that ARE employed. It's a vicious cycle that can only be broken if they lower wages so that more individual people can be employed.
I don't need a high wage; it's one of the reasons I'm considering returning to Newcastle.
