This line of thinking has ruined the auto industry in the US and it's one of the the reasons we have a terrible education system.
If I have a bad worker (even after 7 months), I should be able to easily get rid of them (with cause). As a business owner, I shouldn't have to waste my time going to court or having some sort of 3rd party vote on whether I can fire them or not.
Businesses will never thrive in this sort of environment.
