I think its worth mentioning, you should look at the seniority lists of the job you are bidding on. If you want to go fulltime, look at the fulltime driver list and look at those peoples hire date. Then look at their center date. That is about how long it takes to get that job.
But yeah, full time is full time driving. then there are the PT drivers in the morning and evening. Then you have cover drivers, which it is also worth mentioning, can be dropped back to pt at anytime. Its kind BS because you never know when you are going to drive.
