I got sued by the internship for this….

So I had a meeting today.. With the headmaster or whatever you call it. The boss over the principal and school (preschools as well). I told the headmaster (operation manager, but that sounds odd) exactly what happened, how I have been treated, and how everything has been and is. What I and two witnesses saw/heard/experienced in the meeting, etc.
It felt like a positive meeting and the boss was very shocked and super concerned about the staff etc at the preschool and school.
She would start massive investigation about it all. Try fix so I can continue the education and remove the F’s I got in two subjects due to lies and made-up-stuff they all have said. She said everything sounded so odd and she also explained to me about the report. Yes I got sued at my internship for saying no to a child who abused another child.
I wrote this earlier but I tell again. I got sued by the staff and principal at my internship (preschool) because I said no to a child who smacked another child in the face with fists, and the two staff members who were outside (this happened during recess/playtime outside) had their backs towards the situation. I was 10-15 m (meters) from the situation, so of course I said no out loud. But yeah. Apparently I wasn’t allowed to say no to the child.
So automatically my teacher and the principal failed me in two subjects . Note that one of the subjects lessons didn’t start until last monday (11th of May) and my internship ended 30th of April. Still she has failed me. How?!
So hopefully this will be solved and I can continue to move in the shadows. Let’s see.
