Secondary teacher of a practical subject. Maximum amount of students doing practical at one time has always been 16. Suddenly this term it has increased to 25! Boys school so big kids, year 10.
Head of department has decided this particular practical should be taught. I feel it is dangerous. Multiple hazards, too many kids, accident waiting to happen,
AIBU to say I'm not doing it. WHEN an accident happens I will be held accountable as class teacher.
