BALPA changed its position from insisting something needs to be done to now saying it is hyperventilation. Why? How?
Well... discounting the rumours of blackmail - of which I have not heard of any real evidence, look at the personnel changes...
2009 Dr Rob Hunter left the CAA to become BALPA's Head Of Safety - a new (highly) paid post created for him. BALPA later start using Dr Mike Bagshaw as a consultant to their Ops. Av. Med. Group.
When the rest of the world acknowledged this problem, but UK did not, Mike Bagshaw was head of British Airways Health Service and Dr Rob Hunter was head of CAA Medical dept.
CAA and BA cannot go back on their earlier view because it makes their earlier decision reckless. Did they instead change the BALPA stance to align it with the old CAA/BA position, making it easy to say later that "we all got it wrong so it wasn't us failing in our duty of care, it was a lack of compelling evidence?
IMHO this UK disgrace apears to be down to just 2 people - Dr Rob Hunter and Dr Mike Bagshaw. I suggest BALPA members need to take some action against their union.
