Apparently teachers have had a significantly lower death rate from Covid
than the wider population, after correcting for age and gender. The
greatest risk of schools reopening is the journey to and from the school.

Which in my experience is, for teachers, overwhelmingly not on public
transport. Apart from anything else it's not reliable enough to
guarantee to get you for 8.30am, not a minute later.

Also, many bus routes avoid schools before 9am, because they don't want
the hassle of kids on stage buses (yes, I've discussed this specific
issue with a bus company when writing a school's transport policy).
