Well, actually it would depend on the satellite center circumstances and your Supplemental language.
For instance, in the Central Region Michigan Supplemental a permanent change of over 50 percent by total stops of your bid route, area or loop or a start time change of more than one hour allows you to follow the portion of your route that you want to that you have the seniority for or to bump any junior driver.
So it would depend on the specific circumstances and your Supplemental.
