When I worked abroad with IAL I swapped a few duties in order to take a fam flight home with my wife and new son. On my main leave I was amazed to find the days I was out of the country were deducted from my leave!! When I took it up with the manager later he denied all knowledge, despite the fact that he had partly organised it!!!!!!!!!!!! Good old IAL!!
100 days leave at Heathrow? Well, almost. The watch roster plus leave meant I only worked 179 days per year if I played the leave right.
