now that's not particularly sensational, and that's where the drugs and the alcohol abuse level comes across, and that is the emotive term, but what i'm saying really is the symptoms which that teachers are displaying of stress manifest themselves in an increase in er abuse of alcohol which could only be the odd extra drink, or the odd 5 cigarettes a day, and sleeping tablets, and that becomes an issue when you haven't got a teacher who's not in control the following day, but you certainly have a teacher who's not 100%, and that's where the effect on the child tends to occur.
