If the crew member is sick, just make sure the call is done with plenty of time within limits and with a good sick note from the doctor, then any questions are already answered.
Funny you say that. From what I hear, the guy called in sick 26 hours before report time. Provided a very detailed sick note (which was verified by the company) yet, was still hung out to dry! As for the Facebook "evidence", (which was NOT a picture) funny how that all came up AFTER the poor buggar decided to appeal the case! I smell something funny, don't you?
