This came as a surprise to me. I don't really mind but I have a couple questions: 1. What am I going to get paid? Is it 4 or 8 hours straight time holiday pay (my regular job is part time preload) and then time and a half for actual hours worked? 2. If I'm still in my 30 day probationary/qualification period for cover driving does the requirement apply to me? 3. Am I required to work the preload if they don't actually need me to drive?
