Work is a 2 way exploitation.
IF, you could get more pay for less work, a closer commute, nicer working environment, more flexible working, more praise, and more security. You'd go and get it.
If they could employ someone on less money to do more work, take more shit, and more unpaid overtime, they'd have done it.
So whilst the equilibrium is there, both parties are exploiting the other.
Currently. In some parts of the country in some industries, the balance is for once in favour of the employee.
Hence care home staff, saying "Go on sack me for not having a jab" or bin lorry drivers saying "I'm off you cunts "
And companies saying "do you know anyone that wants a job?"
Brexit has fucked the fine balance where companies could pick and choose, and employees could take it or go on the dole.
