Whilst UK employers have a legal obligation regarding the releasing of their employees for duties with the armed forces I wonder if this differs for pilots? For instance if you were mobilised for what could now be up to a year, we would be unable to simply return to our duties in the LH/RH seat without additional training, this would be both costly and time consuming from an Airlines point of view, not to mention the disruption caused by our absence. Unlike Doctors, Nurses and other medical staff who when mobilised would most probably be employed in their respective civilian roles it is most unlikely that we as pilots would be employed as such unless of course we were ex military pilots who had left full time service recently.
Like most of us it's taken me a lot of time effort and money to get to where I am today and whilst I'm keen to join the Auxillaries if it could cost me my career I would have to reconsider.
