Remember to conduct yourself internally assuming you will have a public audience. Because someday you might.
Was recently discussing a legal retention requirement in company chat. Made sure to be completely forthright and formal about responsibilities. Can’t play with that stuff.

We got an all-employee email from a higher-up, maybe 6 levels down from the top.
(paraphrased) "Make sure to always write your emails as though they'll be above the fold on the Washington Post... *AS MINE WERE LAST WEEK*."
(emphasis mine)
Of course, this was the FDIC. But still, good advice.
