Lucifer there are a minority of crew that take the p*ss with calling in sick, but this is a minority .
You have to remember we are the only group within the airline that is actually financially penalised if we call in sick as we lose our allowences, which make up the bulk of our take home pay. Perhaps there are some girls (and boys) with rich hubbys that can afford to take the mick, but for the most of us going sick regularly just isnt an option if we want to eat!
I do agree that BASSA needs to take a firmer stance with those crew that simply are not flexible with their working hours (hello its an airline!) and that call in sick every weekend, xmas and easter. But don't mark as all as the same.
I think that within every department within BA you will find that 80% at one point or another have called in sick when in fact they aren't.
