You should also negotiate minimum standards for newhire pilots in there. I don't think I've ever seen this before but it could be very beneficial with the upcoming "pilot shortage" / massive hiring / whatever.

All pilots hired at Delta shall have:
Civilian background-
3000 TT,
1000 Turbine PIC

Military flight training successfully completed-
1000 TT
500 Turbine PIC


Or whatever you guys feel appropriate. Keep the standards high. That'll help combat a lot of downward pressure in the future. They'll have to keep wages high to attract the qualified applicants when there is a shortage of them out there.
