Asian Eagle,
I am more making the point that a regulatory sim that is not complete for whatever reason, be it sickness or poor performance has a huge multiplier effect and burden on Crew Control.
Eg sickness, the sick guy may have up to 10 days or so of normal flights cancelled requiring a replacement pilot for each flight before he can be rescheduled for his regulatory sim (if he doesn't agree to work on G days).
Then another sim slot with crew up/other pilot AND STC has to be organised on an already tight schedule.
Sims are important and shouldn't be done if you are feeling tired/fatigued or sick which you probably wouldn't know until the last minute, requiring a crew-up pilot to be called off reserve to replace you.
All huge disruption for one event. Just look at what happened when a checker with an invalid check authorisation signed off PCs recently.
Of course not doing anything during Christmas, New Year, CNY and now easter has weakened the effect of any CC. Yep great chess move to lump in all negotiations together on a good faith basis and wait for all the peak periods to pass. I mean who would have expected them to want to cut crew complements when even in the FAQs for the new AFTLs GMA wrote There is no intention to reduce crew complements on both three and four man operations pending the conclusion of RP negotiations. Yep the recent announcement was a complete surprise.
