Especially if the students have a mailbox in the classroom where graded papers, notes and invitations go, then disappear into the backpack Narnia.
I know from experience.
We have a meeting set up, a half-day retreat. A VIP is going to speak. I booked a room for it, but was told it was going to be at another venue. I did not cancel the room I booked, because I have seen nothing concrete about the other venue, only know that other venue was mentioned to several staff by the big boss.
Direct boss, who is in between me and big boss and in charge of all other staff? She doesn't know anything about other venue being an option due to their prices. This event is in less than two weeks and I am in limbo. Big boss is out of town.
