I know that things have tightened up a lot in some areas.
When I was training to become a school teacher the lectures on safeguarding - and self protection - were very specific and detailed
Then every school I taught in made sure that every teacher knew the rules and requirement
things like never in a room alone with a pupil unless in clear sight of the door and the door open.
It was partly in place so that false accusation couldn;t be made - or not easily - but also so that teachers (etc) couldn't take advantage of a vulnerable pupil
When I spoke to old teachers (and ones my own age that had started teaching right from school - I started when I was over 40
) they said there was none of that when they started
In fact at that time it would be normal for a teacher to have a detention or after-school session with only one pupil and close the door.
At times they were 'rumours' of a member of staff 'having wandering hands' around the girls - or something
That was totally impossible in any school where I taught - OK probably not totally but way more difficult and unaccepted than years before
