In the UK, if you are on a low wage, you can get top up money from the state, if you meet the criteria.
Guy at work gets in work top up credit wage
Managers want him to do overtime
He refuses, as “this will affect his benefits” (true)
Managers REALLY need him to do overtime
Are they willing to pay him more, to take him out of the low wage bracket.
No
So he refuses the overtime (quite rightly) as he refuses to take a financial hit(also quite rightly) to help them out, when they will not help him, by paying him more.
Managers grumbling “as no-one wants to do extra anymore”
The cheeky gits pay starvation wages and then whine if the staff won't stay over.
We owe them nothing
Basic pay gets basic effort
