We used to get credit for a SC if a trip had a report time prior to 1200. When they droped the number of SC days down to six from eight, that provision was also dropped. So we no longer get a SC credit if they assign you a trip prior to 1200.
On another note, I had them assign me a 0500 SC the other day. It was on my schedule the day prior, but I never acknowledged it because I wanted to see when they would actually notify me of it since I have always just acknowledged via I-Crew. They finally called me at 0400 to notify me of a SC assignmnet that started one hour later. Since I already knew about it and wanted a SC credit, I just said OK. I did let them know that they should probably have notified me 11 hours earlier.
