On why he refused to work 6(!) trips at a time when everyone else in the company were having to pull together to get through the severe disruption that the snows brought:
"my first responsibility is to the union so I won't be turning up for my trips"

His dedication to the union is commendable but I think most employers, and many hard working employees, would wince at those priorities.
This is a guy who believes he has been unfairly dismissed and is mounting an appeal. Yet he has been silly enough to go on national radio and have a rant, during the course of which he has said rather too much for his own good.
It is sobering that this is the calibre of union rep upon whose skill the future conditions of so many cabin crew depend.
