Forget SAP, Just call in sick for the days you need off.
The company sells SAP as a benefit to the pilot group, but the truth is, SAP benefits them just as much by allowing pilots to arrange their schedules around the days they want off, therefore reducing the total number of sick calls.
Since the process in place to reduce sick calls is failing then we have no option but to rely on the previous process.
Make sure your wait until less than 12 hours prior to show time.
