@lhdrvr these matters seem to be handled differently by each terminal / linehaul manager. I am not aware of any broad 'corporate policy' on such matters. I can tell you that at HAR, it can vary. Usually if a new run is introduced it is put on the board for all to bid on. If a run becomes vacant for whatever reason then drivers can bid on the run starting at where the original driver was on the seniority roster at the time of the original bid. Often, new runs or vacant runs will be covered by extraboard drivers, and these drivers aren't always chosen based on their seniority. So it's a grand mix of how it's handled, but usually runs are bid on by drivers - extraboard or not.
