link to article if you're a teacher, lecturer and in the UK you can join NUE (formerly NUT), these guys have kept the eduction system in the UK working for students for since 1870, my parents were part of NUT and theirs before them! Ask comrades, ask libs, ask chuds, find their local union and get them into the movement.
Even if you can't join a union (private school, charter school, etc) you can still protest reopening and stage work actions (refusing to teach in school and only remote teaching) as well as talking to your colleagues about doing actions in concert and joining a union (although probably best to use personal email to communicate). You are protected by the law to do that (although discouraged obvi).
And to unionized teachers, you are also allowed to stop/refuse working in-school and it won't violate no-strike clauses (which most American unions have in their collective bargaining agreements, thanks CIO), just make sure to cite unsafe conditions as the explicit reason
Good primer on using section 7 of the NLRB to protect yourself and your actions (written by a rank-and-file labor lawyer and an IWW organizer)
