Quote from Milk;1197395:
Yeah no, there are no legit ways to get out of it. And even if you do make an excuse you will be re assigned to come in at a later date that month so its not like there are ways to get out of it. And if you do lie about certain things and they turn out to be untrue you will be forced to pay a hefty fine. Refusing to do it also ends with you having to pay a fine as well. So its either get your free money / essential days off where you just sit around doing nothing half the time or pay them a couple hundred bucks because sitting around is to much of a pain for you to do for a couple of days.
I told them once I was sick didnt have to do a summon or reschedule your point is invalid
