Culturally Insensitive Teacher

A teacher is in front of her class of teenagers. Mid-lesson a teenage boy (from another class) strides purposefully into the room, without so much as a bye-your-leave, marches to the desk of a girl pupil (his younger sister) and sets about bashing her.

The beating is fast, savage & expert. By the time teachers have intervened, blood is drawn, lips are smashed, her dress is torn, bruising and black eyes follow.

How was this handled by the teachers?

The Police are not called. Instead the Teacher whose class was interrupted gives the boy detention, or lines to write out (or something equally mild) as punishment for interrupting class & failing to "show respect" for his sister.

A day or two later the teacher is again in front of her class. Mid-lesson a woman (mother of the abovementioned brother & sister) strides purposefully up to the Teacher, without so much as a bye-your-leave, and with brutal swiftness sets about bashing the Teacher.
The first blow knocks the Teacher back over the teacher's table. The table is tipped over, the Teacher lands with a thud on the floor. Class props & student projects are sent flying as the woman's intensely physical attack on the Teacher continues.

This time the Police are summoned. The woman is taken away by the Police, all the while loudly proclaiming that nobody "interferes" by telling her son how to handle his sister AND gets away with it.

The Education Department tut-tutted aplenty and pressured the Teacher into not pressing charges against the woman. The police "investigated" & found no charge to stick the woman with.

The Teachers Union didn't wait for the Teacher to contact them. Instead the union's senior official in the nearest city immediately made a public statement that they would be helping the Teacher with counselling on the matter of cultural insensitivity, and that Teachers in general should be more culturally aware of the norms of the towns in which they teach.

During a newspaper interview (on another matter) the reporter seeks Mine Host's opinion on, amongst other events, the recent high school "incident". Mine Host, having just read in the press the comment by the Union, gives a quick opinion on the topics of:
Protection of Members (union abrogation of),
Common Assault,
Public Disorder Offences,
Safety in the Workplace (as viewed by the Trade Unions)
Classroom Discipline,
Liability of Employers who fail to take measures to prevent staff being assaulted at work.
And a quick character opinion & suggested alternative career of the union official who made the reprehensible statement implying that the Teacher brought it upon herself.

The reporter blurted: "That union officer is my daughter!"
Then calmed down Three seconds later & said "By golly, you're dead right though, I've never thought about it like that before!"
