Teamster251 this is a company policy and has been for a very long time. I believe it is a very fair rule. there is "NO" seniority violations going on here. Linehaul work rule No. 2 "All scheduled runs have priority over extraboard drivers and all attempts will be made to keep the schedules running by substituting loads and running drivers through other locations to keep them on schedule. If a schedule is still cancelled (schedule will in now way be able to run any part of the planned run) the driver will go to the bottom of the extraboard."
