No, it is probably not likely you could hold a line right out of training. You will be on reserve anywhere from a few months to less than a year. In the past, the line values went up and down depending on the time of year.
For the first four months this year, the average line value was 95-100. Obviously, that is not sustainable. Historically, the fall line values were 50-60 hours, but they have been trying to even out the schedules. Until they get staffing closer to where it needs to be, the line values are going to remain high.
