I also lean towards benefit of the doubt.

I guess I just don't understand how a person with issues at home benefits from floating? Is it to get paid an extra 5 hours a month? Or to be able to drop trips using FMLA and get paid?

If it's the former, and you're a captain that can't live on 73 hours a month, you have some serious financial issues that might require a change in lifestyle. If it's the latter, that makes some sense.
