In the good old days of the charter airlines I would help them out by working a day off because almost all standbys ending up as days of and I was respected by the management who regarded be as a professional business traveler and used appropriate hotels.
In the lo-co life has changed, almost all STBY days end up as work and the rest you get after long working days and being sent to cheap scabby hotels is limited.
The result of this is not working days off is not any sort of revenge or political action aganst the management, it is simply a fatigue management tactic so that I am safe to fly on normal working days.
