What the?
Any pilot employed into VAA will be on current VAA terms and conditions. Any pilot employed into VAI will continue to be on VAI terms and conditions and not some B scale VANZ contract. VANZ pilot will continue on whatever EBA they manage to negotiate. Like it or not NZ is a different country with different industrial laws and requirements. Superannuation, insurance, industrial law are all different. You can't expect any and all conditions to be made available to all parties across different countries.
Skywest will at some stage also be included into the seniority list but they will retain their own T & C's. if they choose to move to VAA, then they will then be employed under the VAA EBA be it better or worse than the Skywest one!
