They call during that rest period because the assignment can only be made 48 hours out and that means they only have an 18 hour window to properly notify you. They have missed making that call by an actual scheduler many times with me. That's if trip is in open time prior to the rest period. They can't even cover trips in open time on time with regular reserve availability because they let them sit. They may have a "good plan" but they fail regularly on execution.
