I'm rostered on today but need to check whether my medical has been reinstated before performing duty.
Perhaps I've missed something, but why would you be chasing AVMED on the day you have a duty shift, instead of (say) the week before?
In my organisation I'd get a blast if I hadn't sorted things out myself well before. In fact there's a management instruction that we're totally responsible for ensuring our medical is valid and up to date.
