A friend of mine has been threatened with being banned from her son's school premises - she has been accused of being a bullying towards a member of school office staff on one occasion. She says she did not swear or use threatening behaviour. It appears the Headteacher has not carried out an investigation but taken the side of the school employee. She wrote my friend a letter, with a copy to the local borough solicitor. What can she do about this?
Presumably though since you say 'threatened with being banned' there actually won't be any consequences provided there is no repeat of the confrontation.
