It's really very simple....
Do you know how much money people make from writing books on diets and health regimes. When we all know it's calories in vs. calories burned that make you fat or thin?
It's the same here in as much as we all know what the problem and the solution are.
You whinge, but stay = no pay deal. You leave, they listen = everyone else that stayed gets a pay rise.
The fact is that you won't leave because you are in 'the system' that says that if you stay with us you will benefit from having a high seniority. This industry differs from many in that seniority, rather than suitability, pays off when it comes to promotions etc.
So you stay in your chosen company hoping that they will reward your loyalty.
In England we call it being caught by the short and curlies.
