To most of the commentators saying "why work when you're not getting paid", please correct me if I'm wrong, but aren't federal employees not paid during a government shutdown getting retroactive pay once funding has been restored?
Even if they will (which shouldn't be in doubt, but these are not normal times) it is still when they are not getting paid now, even if they will be paid some time after an event which is expected to occur at some uncertain time in the future finally happens.
