My DS' head teacher has just said that he can refuse to physically release a child from school to parents if he hasn't granted permission for the absence. This stems from the last Friday of summer term when I wanted to collect DS 1.5 hours early to collect DH from airport. The head opened the door 2 inches while he lectured me and decided if we could go. Bearing in mind DS had 2 half days off all year I felt this was heavy handed so asked for a meeting today to discuss. He maintains he can refuse to release my child to me in school hours. Is this true??? Although I have no future plans to collect him early it makes me uncomfortable being told I could physically be prevented from having my child :-(
