Reported a close co-worker for physical abuse of a child the other day. It happened in a moment of frustration and I could tell they regretted it afterwards but another staff member and I saw it and decided we needed to inform the supervisor. They're probably going to lose their job and there's going to be a police investigation.

I feel like the rest of my colleagues are judging me for being a snitch now and I feel awful and a little like reporting it is going to cause me a lot of grief in the long run but how do you not say something?
