A guest poster at Hook & Eye makes the case for keeping a list:

Despite the gloom that lurks over making such a list, I urge you to make one of your own. Include dates, times, places, people present, and include whatever evidence you can. Evidence can be documents, photos, emails you sent in regards to an incident, emails about setting a meeting time to talk about a concern, your meeting notes or official meeting minutes. Write a few notes on how incidents and concerns are dealt with. Perhaps a concern was dealt with and the resolution impacted your department for the better. Note that, too.

Hopefully, your list will be nearly empty. Maybe it won't. I'm not suggesting that you make the list to take formal action at the equity office. Just document things as they happen. Maybe you’ll never need to use the list.
