socalrca -- "Does a PTF have to bid on the next vacant route or is it given to them automatically ?"
-- Page 26 of the current contract: If a vacancy still exits, it shall be awarded to the part-time flexible rural carrier at the office with the longest period of service in the office as a part-time flexible carrier, who will be converted to a regular carrier. In no instance will a part-time flexible rural carrier have the right to refuse conversion to regular rural carrier.
-- So, no, the PTF does not have to bid on the next vacant route, it will be award automatically.
-- However, if there is more than one vacant route, better bid on the one you really want -- just in case.
