Hi, I was recently offered a job as a PT sup, either as preload sup or morning OMS. I'm currently a casual driver in the winter and summers and have been for 3 years. I've read several threads here about these positions and most people say not to take a PT sup position because of poor treatment. But that isn't what I'm here asking about. I'd like to know specific responsibilities and struggles for each position from people with experience in these positions. What should I expect going from a casual driver into this new position?
