After seeing week after week how my greedy trainer demands more money I thought how unrealistic and not fun current staff system is. I know that current system is intended to keep staff market alive, but I suggest a better way in my eyes to do this.
What about specialist trainers, for example big man and guard trainers or offensive and defensive trainers (specific specialities can be discussed). Their salary would be flat or would increase a small amount in offseason. I don't mean that for example guard trainer you can't train big men, but I think that trainers should have different skills like players and those skills would have different values from 1 to 7.
Of course this system could transfer to doctors and PR-managers to somehow.
This idea isn't mine it's from online volleyball manager game vm-manager.
