Over the past few months I have witnessed a couple of Zoom meetings between a teacher and a teenage pupil. Just made sure that the background is clear and without revolutionary type posters, Kalashnikov pics and such ... knowing that Zoom can be hacked etc.
Also not sure what is the relationship between teachers and social services here in the UK. I expect it may be triggered in the case of vulnerable pupils (thinking of secondary school level). Anyway, one can apply basic precautions (bland background) and bob's yer uncle : ).
