Your method is the military method Guvnor.
It sounds fair, but even in a Military environment it doesn't work properly because of "preferment" and "interest".
As to civil airlines, I like the "apples and oranges" scenario. Well said that man.
Problem is the human nature factor. Everyone tends to believe they work too hard for too little, and resents anyone earning more. This characteristic is then exploited by senior management emloying their own version of the Military method.
Cynical - you bet !
