Kind of a historical note on the voluntary furlough issue.
Last time we furloughed the choice was voluntary or involuntary. Initially, those who chose voluntary furlough were going to receive benefits during the furlough and those who left their fate up to the displacement (involuntary) would receive nothing. So most of the people who chose the voluntary option were junior FOs who knew they were going to get cut anyway and just wanted to keep the benefits (me). Somewhere in this process they changed it to where every furloughed pilot received benefits.
I guess the futile point I am attempting to make is that, as the previous poster mentioned, I wouldn't expect many people to take the voluntary option. COLA's are a different story.
