The way this was communicated to me in the past was "don't say/write anything using company resources that you don't want to see on the front of <insert major news publisher>". All communications on employer-operated platforms are subject to discovery. Senior leaders tend to skirt this by using the telephone or video calls predominantly. However the infiltration of machine learning and AI means transcripts of calls, etc are now possible too. In addition, the growing use of "disappearing" messages despite litigation holds has come up in more legal cases recently.
