Dr. Upton did not have a right to be there. He had, apparently, sought permission but the person who agreed had no authority to grant it, as there was no policy in place, and certainly no discussion with female staff members had been conducted.
It was made perfectly clear to him that his presence was making the female occupant uncomfortable, particularly as she was dealing with the consequences of a heavy menstrual flood. Any considerate person, male or female, would have left immediately, instead of which he insisted on staying and began to undress, apparently determined to provoke maximum embarrassment. Such behaviour from a doctor in particular was reprehensible, and from a much younger man to an older colleague, disrespectful.
He then compounded his actions by spending the next day, Christmas Day, attempting to get Sandie Peggie sacked. An extremely unpleasant person, and highly unsuitable for the medical profession.
