You only get the PBDs if you will have your moving days after DFW closes (Jan 31). If you have your moving days scheduled in Jan or if you already had them, you wont get the PBDs. In 5.A.5 of the contract it talks about these 4 consecutive days off, those are the PBDs (but NOT your moving days). Your moving days should be mutually agreed between you and the company.
So basically if you get your moving days in Feb sometime, you get an extra four days off following your last assigned DFW trip. IF you got your moving days in Jan, you do not get the PBD days. Clear as mud? And you can work on the PBDs if you request it and they still count as the 4 consecutive days off.
And it has nothing at all to do with the moving money.
