We place a less restrictive filter on staff (mostly to "warn - click to continue" on things that would be blocked for students so they don't set blocked URLs as homework), but as part of safeguarding we're required to filter our links for everyone so that a student might not see something upsetting on a staff member's monitor as they walk by.
I don't deny that seems somewhat absurd and our students are considerably more worldly wise than the people who write these laws seem to think but the rules are the rules
