I teach in FE and masks will be required for everyone in corridors and communal areas. Classrooms have been configured with 2M distance between students - so a pre-Covid class of 30 will now be group A and group B, 15 students in each - and from the lecturer. Lecturers can wear visors if they want, but H&S are confident in the precautions in place.
We’re doing a blended learning approach so the number of students (and staff) in the building will be hugely reduced. (Instead of doing four full days in, I will do two half days of face-to-face and the rest remote teaching from home.)
Interestingly, staff, including security, are not allowed to challenge anyone without a mask, due to people potentially having hidden disabilities. So who knows how many students will comply.
