In my school the Head had said that it is unreasonable to tell the children to do something because it is imposed by he government and then as a school choose to pick and chose which to adopt and ignore. Those headteachers who do so set a very poor example and dangerous precedent to the children .
The precedent of thinking for yourself? That's a good thing! Especially when children are choosing to adopt safe and wise practice in a pandemic, mindful of the safety of unvaccinated teachers.
Wearing a mask is a sign of courtesy and respect for others' well-being.
