If you are a QUALIFIED feeder driver that is laid off, you are, indeed, entitled to run whatever run that contractor is taking. If not, you get paid for it. BUT!!! You have to document the times, numbers, contractor number and FILE! OK, sure, maybe not all this info is necessary, but it sure cements your case.
This is an absolute no-brainer. Any and all QUALIFIED feeder drivers that have had to take a lay-off or bump into the hub is to run these runs, whether it be for one day or a whole week.
Now, you're going to say that those QUALIFIED feeder drivers that are in p/c have to fill out the whole week there and not move back and forth from day to day. Well, that was tried here too and didn't fly. It was grieved and won, MANY TIMES. Try it.
