I often used to wonder whether my school was built over a plague pit, such was the level of illness. I don't mean the kids, I'm talking about the staff.
Whilst most teachers realise that they are actually supposed to come into work and are good attenders, there is always a hardcore group who are forever off and amazingly, nothing is ever done about them. Their reasons range from the vaguely believable to the utterly bizarre. (Strange allergies, mysterious 'viruses' and 'flu' every time the wind changes direction- a disease specialist would be fascinated.)
Short and regular absences are simply accepted without question and for longer ones, it's well known that a doctor will sign you off just to get you out of the room and even if they won't, no problem- just ask for an appointment with a different one until you find a soft touch. If I had my time again, I'm not sure that I'd ever come in at all.
What I never understand is why most of the other staff just accept this, muttering about "not giving it to the rest of us" despite it being well known that most infections have passed the contagious stage by the time you even realise that you are unwell. It's considered taboo in many staffrooms to criticise those who are 'attendance challenged' and unfortunately the vaguest mention of 'The Unions' is enough to make most Heads (who often don't know much about the law, but are very aware that they won't receive any support from the Council anyway) back down from taking any action in the face of skiving that would have you sacked in the corporate world.
Compare this laissez-faire attitude with that of our more successful companies who employ a doctor whom the staff must see as well as operating a 'managed return to work scheme' where the person who is ill is regularly monitored rather than just being allowed to fester at home. Funnily enough their absence rates are half of what ours are. Every time one of the workshy plays the system, it simply gives the Government more ammunition against us.
Until teaching gets a grip on staff absences, we will never be taken any more seriously than Council workers.
