Go ahead and flame me if you want, but these arguments against someone wanting to bring their pay back up to what they originally had without going over is silly and stupid. They are not helping the company or hurting furloughees either way.
In my career with the airlines I have NEVER picked up open time, only dropped what I can't handle with my other employers schedule. However, I am not going to fault someone - most importantly an FO who is making 30-ish dollars an hour for trying to make his pay whole while adjusting his schedule to fit his needs, IF he/she is even able to. Kudos to them for even being able to.
I am willing to bet that those who comment negatively against others who even suggest such a thing are two-timers and would do it with a slight chuckle if the time came to where the option afforded them.
Whatever...
