"BALPA were not allowed to be included in talks with the VNV and the Air France Pilots union regarding future harmonisation of the workforce."
I hate to sound ironic, but neither were the pilots of Japan Airlines. I am only guessing here, but I presume you don' t have a contract with KLM but with ??KLM-UK??. I guess the current setup is sth like KLM leasing pilots from KLM-UK. A great setup...as long as it lasts.
"LLuke, the BALPA CC has tried to have a constructive meeting with the VNV for several years. Each time a meeting is arranged, it is cancelled the day before with some reason or other being given. It is clear that the VNV do not wish to have talks with BALPA."
There are people from the union daily/weekly in the BMC, BALPA and VNV are working closely together in the ECA, presidents from BALPA and VNV are now president resp. vice-president of ECA ...
... and your BALPA representative is not able to arrange a meeting?
Before you have this 'constructive meeting' also don' t forget that you have your contract with a company, not the VNV. The VNV can only give information/advise on what to do to improve your situation.
I consider you as much a KLM pilot as I am, but your current contract is not going to do you any good.
