Are you asking about the places where we actually work? If so, I imagine that most of us would have no issues with our supervisors' level of commitment to occupational safety. As teachers, we are not typically exposed to much in the way of hazards. We face potential hazards, of course, from things like fires or school shootings, but we have drills and procedures that are meant to keep us and our students as safe as possible in situations like these.
The only issue I have ever heard expressed is that some teachers (not at my school) have felt that they are not adequately protected from students who might be violent. They feel that principals are not sufficiently tough on students who start fights and who might assault a teacher.
