In “good standing” used to mean no write ups for the 6 months prior to a transfer whether it be to another job class or following the freight...well, no signed write ups anyways.
We once had a guy who got to transfer on the technicality that he didn’t sign his write ups (he had 2 or 3 at the time)...ended up costing another driver around 10 spots in seniority!! I’d advise everyone to not sign anything!!
