In your system, those that will be "productive" and prized by management will be those that.
Always hustle
Show up on time
Are great with passengers
Do a little extra
and then......
Fly with a cold
Take the broken airplane
Waive duty time to finish the trip
Waive required rest
Take off during thunderstorms and wind shear
Refuse to divert
Always complete the trip
Cross every picket line
Fly with minimum fuel
It is a slippery slope that you start down when you allow for a ranking system within an industry so dependent on safety and judgement. Fear of retribution will influnce pilots innapropriately in your scenario.
Safety WILL suffer, and that will ruin the profiability you seek in the long run.
