Nobody is being exploited? Really?
Businesses do it all the time. Many business owners see it as part of their business strategy, to get as much out of people for the least amount of money possible. I used to work for a company that did exactly that, leaving me mentally broken.
The law in the UK is even on the side of these business owners because for most of the past 40 years, since Margaret Thatcher & Reagan (Who shared the same economic philosophy) employment laws have discriminated against the workers.
In my case I was told the law couldn't help me because I didn't have any evidence. What evidence was I supposed to have other than the facts of my mental illness that I didn't have when I started working at the company?
The whole system is based upon putting profit before people. Just one example - why is it acceptable for businesses to hold money offshore yet individuals cannot? As I said, the whole system is skewed in favour of the corporations because that is where the money - and political donations - comes from.
Employment is at the will of the employee. If you are getting exploited it is by your own choice.
