I have a common friend, who is an Asstt Teacher in a Non-Govt aided school and where the Headmaster is very dominating and self-opinionated. Recently he installed a CCTV camera in the staff room amounting to the invasion of the privacy of the staffers. When objected, he retorted saying there is a provision for this. Is this really so or is he trying to intrude into the privacy of the staff? Is there any legal way out?
