I agree with all the above. Keep it short and simple.
My list.
20% pay increase minimum (2 steps + VAT + Inflation)
78 hour OT threshold with a punitive scale. Exceed 84 hours and OT pay rate doubles. Exceed 90 and OT pay rate triples.
Credit hours for leave and sim. 3 hours per leave day. 5 hours for sim or ground duty.
Drop restrictions on rostering requests and on swaps.
Offer life style rosters in seniority.
