Let's not moan about not being paid for post flight duties, SEP, etc.... After all, we get a salary...
There was a time when there was a credit for SEP, CRM, Sim Duties, in fact pretty much everything we did including leave attracted an hourly credit that would sometimes become a payment depending on how much else was done in the month. At that time nothing was paid until 84+ hours of credit was reached and at that point productivity kicked in.
The payment for non-flying duties disappeared around the same time as the first 'cost neutral' salary adjustment but the credit remained in the background so as to build balanced rosters. It wasn't cost neutral but at least what they had done was 'visible' and rosters were still constructed sensibly.
More recently they removed the credit part completely, this was unannounced and remains unannounced. This means that crew can and often will fly a full 92 hour roster and on top of that might spend two days in the simulator and have a day or two of ground school too. Another scheduling favourite is to have 10+ days of leave and still be assigned work close to the 92 hours cap. The 92 flight hours is a target regardless of any other duties.
But let's not moan.
