Im pretty sure all offshore contracts have a short get-out clause. If its in a contract then its perfectly acceptable from a business sense. From a moral standpoint? Well thats for the individual to decide.
I was led to believe that offshore workers wanted to spend less time in helicopters, not more, but are they now saying they want to spend less time travelling overall, hence direct helicopter trips instead of having an additional fixed-wing sector.
Lets hope Scatsta and Sumburgh can survive, if this is to be a wider industry decision.
