Good head work to print your schedule after the 3PM check in. I've had Short Call periods put on my schedule twice where there was no notification of conversion. I was blissfully unaware until the phone rang at 05:30 to "remind you you have SC at 06:00"
ACL, Bucking, and several others took to printing their schedule daily to a PDF file. I'm not claim any malfeasance, just pointing out it is easier to prove you looked (and to be sure you looked) if you save the output.
