adenuffofqf - I think we all have, however I have to disagree with the fear campaign being spread by DC and the Oompalumpah. The Alaea has had advice and issued it in a memo, QF can't call you up at home and dock 4 hours pay if you are unavailable.
If you happen to be sick of being intoxicated each time they call, try "I'm providing primary care for my children during the school holidays", "I'm having a couple of days away with my partner", "I was willing to do extra O/T to help the company with the dispatch reliability problem that 'snuck up' on the management team, but my doctor has advised me to cut back - it's becoming a duty of care issue".
