Noooooooooooo!
Don't even suggest performance bonuses for atco's!
Because they will arrive with (easier to achieve) non-performance penalties.
I turn up, do my job, go home and get paid. It's simple and the way I like it.
Let's not encourage anyone to start to think they can pay us based on performance.
As far as I am concerned if managers want to keep looking over their shoulder in exchange for the odd bonus hey are welcome to it
