Autofeather lays out the background quite well, IMHO, bearing in mind that his is one side of the story only. To put things in context, it is worth noting that KLM sold the entire existence of KLCuk and the UK pilots therein, to the VNV, as a temporary holding company, only in existence till all the pilots went to Buzz.
Nevertheless, Autofeather said.........
The many reasons for this discrimination by KLCuk/KLC/KLM is because of agreements with the VNV and pressure being applied by the VNV to insist that KLM stick to their agreements........
So, what do you suggest?
That the VNV allow KLM to back out of legal agreements?....and where will that end? should they be allowed to back out of any agreement they choose, or only this one?
That the VNV should initiate and seek to make new updated agreements on behalf of the UK Pilots (who are not VNV members)? Is this not what BALPA should have done immediately Buzz was sold?....but are now doing to stern resistance from KLM?
Face it, the VNV is doing its job, as it owes its members. It is BALPA's doing its own job in the same good way that will eventually force KLM to return to the negotiating table with the VNV and update or delete any agreements that are discriminatory to the UK pilots.
