More correctly, ground handling management get bonuses for on-time departures. That's why delay codes and block times are fiddled on a regular basis, so as to either make a delay disappear or place the blame elsewhere.
The handlers get bugger all. Been there, done that.
Slightly disingenuous to imply BE flight deck put safety at risk by rushing for on time departures. And we certainly don't allow the handlers to dictate when we are good to go.
