Here at U for me there has always been a CYA policy in place. I can count on one hand when time were good the number of times I had to call in sick and I always had a note from the doctor and presented it only if they requested. As for the phone calls to your residence, it is real simple, with caller ID, DON'T ANSWER THE PHONE!!!! The game was played for years by flight crews that were on reserve...look at the phone and laugh.....
