I teach in a secondary school, I have not been here long, about six months. Next week I have to attend presentation evening unfortunately it goes on until 21:00 Hrs. I do not want to go home and then come back to be here until 9pm, in fact I do not want to be here at all (this is the first school that I have taught in that has open evenings etc. as directed time. As far as I know a teacher cannot be forced to attend an open evening so should I be compelled to attend a presentation evening just because the head teacher wants to burn up all of the staffs directed time allocation. Any advice?
