This is more of a WWYD and I may have to get this thread taken down if it becomes at all outing but I am in a moral maze.
It is not OK to place your hand over a child's mouth-even in jest- and tell them to be quiet, is it? This is secondary and in a corridor before I get asked for context. Lots of students around. The child did not appear upset and was not angry either. In fact, the desired effect of shushing was achieved...
Would you report this, regardless of the jest involved and/or who the staff member was?
