We all enjoy the Talkback column and expect a certain amount of poetic licence. But Jonathan Forbes's account (Friday, October 6) of his view from the gates of hell, or the prep room door, does raise some issues.
He talks about chemicals being squirted behind the teacher's back. I am sure this does happen occasionally, but if Mr Forbes has evidence about potentially criminal behaviour, the question is: wha did he do? As an employee he is obliged to inform his employer about health and safety problems. I hope, too, his employer has taken some action, because if a serious injury were to occur and it could be shown that the employer had ignored previous warnings, the Health and Safety Executive would take a dim view.
