So you're paying for it? How? if you give up some guarantee are you gonna be expected to work on those days? No... you'll have those days off. So United is paying for it. You're giving up some right to go make that money, sure, so that it can be spent elsewhere. In the case of a cancelled displacement, it may even be neutral or in your favor. Working less isn't the worst thing in the world. You can do some retirement type things.. now. While you're young and healthy.
