However, same equipment bids to a different base is treated differently than a vacancy bid. Very few protections in the contract for such a move. I have several friends that were taken advantage of, (shocking, I know) by manpower planning. They would not activate the new domicile bid because they were short in the vacating domicile.

No protections, no bumps....pretty much at their whim. Usually doesn't happen, but it's not protected and ripe for abuse.
