It seems to me that anyone who flies over 70 hrs a month on a regular basis is lining themselves up for a period of unemployability. If they choose to do so (and are allowed to choose whether to fly or not) then so be it -their choice.
However, if it is expected, rostered or not, then the employer is getting more than his pound of flesh. He/it/they are exploiting FTL - or is this situation normal?
Maybe I should ask BALP the question and/or then the CAA.
BTW it hasn't happened to me yet but...
