Dear Prof,
Well you talk about workers contracts, but who calls the tune, in no time those contracts would be worthless, money and profit rule, way of the world, I would love anybody to argue against that fact.
Here in Scotland we have that battle at the moment, Scot rail, train drivers don't need to work Sundays, it is optional, but money will win, what ever the outcome, the train Drivers might get extra money but they will lose the choice, and that is another black mark on society, workers need unions to protect their rights, why, owners only see money, they don't see people.
