My point is just terminus, that if you start by telling (before) new hired pilots that they are on a working contract (not contractor or freelance) then also tell them that the oilcontract is running for 2-3-5 years before going out to tender. That's the plan, unless the oilcompany choses otherwise, then it could be running down to 1-2-3 months. Basically, be honest to your employees, that is my point, even if that can give the helicopter company problems in the hiring process, like getting enough applications, or people who will sign the contract.
Like I mentioned: people have moved their whole family, sold the old house and bought a new one in connection with relocating. It is people we are dealing with, not just numbers, and terms of termination of a running contract.
