I lived on the same road as the secondary school I taught in, no real problems, children either studied their shoes if they saw me out, said hello or were already at our house as they were mates with my children.
Only 1 caused ever me a problem - and he was non teacher neighbours problems too.
With regard to entitled parents/getting behavioural problems across….
Do yo have cctv? Show this to the parents. It’s not that hard to copy the highlights onto a memory stick. Hard to argue with video - although some will try.
Delivering a bollocking at a parents’ evening……. Easier if the child is there.
Don’t rush in guns blazing - parents get instantly defensive.
Ask the child what you are going to say, Go for positives and then ask gently about particular incidents.
Most children will sing like canaries. Then you can do the mending.
You can also bring in anonymous, fictional, children who have complained/informed you about their darling child’s behaviour towards another child X. That one can be hard to argue against.
It also helps if SLT have been pre-warned and are about and a TA who will move them on when/if their time is up.
Some problems won’t be resolved that evening/term/year. Accept it.
Good luck.
