What can be used as a weapon in a typical workplace, if there's a shooter inside?

Look around the room: Look around the room where you're hiding and find anything that you can use as a weapon. It can be a stapler or sharp scissors you find in the teacher's desk, the hot coffee in the kitchen of your office, or anything that is sharp, heavy, or made of glass. Even small thrown objects can delay a gunman if a large group of people work together.
