I am working in a class called Fal's which is a class with students with various disabilities. We had a sub teacher, and myself a para. We do not have adult assistants in the class that are greatly needed. A student was throwing things. Threaten me and the sub 6 times each. Throw things at students. We had to call in for 2 additional backup staff to assist as we had to leave the room. My school is calling it one of those moments. How do word this information s it was a safety issue? Also, makes other students act out.
