My interpretation was that discussions directly related to each job would obviously be allowed. I'm sure people still need to discuss employment law, immigration law, IP law, etc. for certain roles. I gathered that this announcement is about casual at-work discussions e.g. in the company Slack.

I think we may have differing ideas as to what "DEI" work consists of; because to your response, that work sounds like the typical duties of an HR officer in collaboration with corporate counel, not necessarily, and not specifically DEI.

Maybe my bias as a DEI officer in current and past roles is on the table here-making things a bit cloudy, and I'm just without an immediate means of resolving that.
