It's such a simple formula that seems to have been abandoned many decades ago by most other big corporations . Cathay used to be like that back in the 80's , they took care of us and we reciprocated whenever they needed our help. We didn't expect additional payment for it , we worked on G days, extended when flights went off schedule, or a last minute call out occurred . It was all part and parcel of knowing that we were paid a fair wage and if a family member became ill, Cathay would provide the best possible care for them. We used to get a thank you letter from Flight Ops for operating on a GDO. It wasn't much but it was a nice touch. I had a stack of them . Sadly that work environment has been poisoned to such an extent and has become so toxic that today I wouldn't lift a finger to help out.
