Legally speaking, what is the precedent for recording this interaction? I ask because I generally try to have any correspondence in a professional setting in writing. One never knows if that at some point could be useful from a legal standpoint. For example, if I asked my manager for a vacation and they gave me permission verbally, I would ask for them to confirm it in writing (in an email). But what would be the best way to do this for video calls and meetings like this?
