Lots of us were not allowed to use offices because they are down narrow one-way corridors, or because they are small and shared with other people, not very far apart. We had to book limited other spaces on campus to work there.
Like @DelBocaVista I am frustrated by this thread. This year, I've spent ££££ on office equipment and faster wifi, I've worked through most weekends, I've replied in supportive detail to the hundreds of student emails that come in, and about one in 100 will even bother to acknowledge my response. I've worked so hard to pivot online and on campus as a moments' notice, and back again. I've been stressed and I've missed my kids. I've offered endless extra support sessions, which they don't turn up to. I've taught to a black blank screen and tried to keep the energy levels up even though I can't see anyone and they won't speak.
While I was teaching on campus which was apparently central to students' wellbeing, numbers were appalling. When tiers came in, we were flooded with emails from students saying they were going home to their families for their mental health, and please could we go online to support them in that. When lockdown happened, even more just upped and left, again citing their mental health in most cases. We kept on offering on campus teaching. Even when it was the only thing we were leaving the house for.
And through all this, all we hear is how shit we are. Everything we say gets this AHA response, everything we do was wrong, every instance of students not engaging is because we failed to care enough - they apparently have 0 agency in anything. Unworkable and ill-informed suggestions of what we could do better are presented like gotchas and when we explain why they won't work that's further evidence of how little we care and how we apparently want to stay at home for the sake of it.
