There should really be an explanation posted. I also wonder how they will deal with those people who already booked travel and now have to pay high fees to change their travel bookings.
who books travel 6 months in advance? You haven't even gotten your tickets yet.
I'm a student and I need to make sure I'm not missing any summer classes I may be taking. Also, some people work and may have to notify their supers early.
If you have to notify your "super" six months in advance to get 3 days off, it's long past time to find a new job!
