Tom a Hawk

Oh I thought you meant they actually said in an email that it's not required and that it's at their leisure.

I agree it's maddening that they get to wait till the day before to tell you and then they can still be late(even hours so) without consequence. That is the worst thing about our reserve system. Ridiculous that the FAA lets them get away with it as well. To me you have to know your start time for day one on the last day of your previous block. If it were fixed, upgrade would go much more senior.
