Wondering if I am unreasonable to be concerned about this or if it is normal. At an extra curricular sports club today in 30 degree heat my son, was tidying up kit. He did it in a way one of the leaders felt could damage the kit (I think rolling something up before unplugging something) which I am sure they would have been told about before and, therefore, he, quite rightly, was told off. However the coach made him do 40 press ups as a punishment as he said "he didn't want anyone else doing it that way" and "wanted to make an example of him". My son is a good kid, superb school reports, not a trouble maker, did not want me to mention it, but I am a secondary school teacher and we wouldn't be allowed to do this in school nowadays. The head coach was away - apparently they don't do this type of thing when the head coach is there which makes me wonder.... Is it ok to do this or does it cross a line into physical punishment/abuse of power? Please advise!
