CHC and Heli-one in Europe has a much bigger Norwegian influence at engineering management level so it goes without saying that the redundancies will be in the UK and not Norway. It means that the maintenance work which would have been done in the UK will now be shipped over to Norway even although their costs are higher.
The UK based engineers working for CHC should be considering industrial action in support of their colleagues in Heli-one. CHC know that these redundancies would not be accepted in Norway so they are taking the easy way out by sacking UK workers.
The CHC flying operation in the UK is already very poorly supported by Heli-one due to lack of spares etc and it is going to get worse if this is allowed to go ahead as even more spares are moved from UK to Norway.
