The thinking is that since you're going to be furloughed anyway, why show up for work on the holidays? If you're not going to be furloughed, you're still part of the team and would show up and perform your job like you always did. I agree that would be a pretty slick move on the part of the company if it worked, but I make the assumption that they have some kind of planning involved to recall pilots and that the union is monitoring the reasons for the recalls. But you know what happens when you assume.
