1. Look Busy: Having papers spread all over your desk helps, as do pencils which are whittled down to the eraser. If you have to walk somewhere, keep your head down, and walk quickly (this also works if you’re trying to avoid being called over to do work. NEVER MAKE EYE CONTACT!). Carrying clipboard with you while moving around also helps.

Or just carry a pen in hand (looks like you just wrote something or are heading somewhere to sign something, even if you are just headed for a restroom break).

Honestly I’ve made an entire career by just standing around and switching between looks of “thoughtful” and “bemused”.
