>Companies treat workers well because they have to compete to get them. Not because the government forces their hand. There's always away around government regulation, so it's not really effective. There's always loop hole. So why do companies offer workers good conditions? Because they are forced to by competition.

interesting point, removing free movement of labour definitely decreases the competitiveness of companies to incentivise their roles, otherwise people have a significantly larger pool of possible companies to work for.
