How to deal with a bipolar coworker
Refrain from casually sharing their diagnosis with others.
Show respect for your coworker by keeping your lips sealed regarding their condition. If their diagnosis is not common knowledge in your workplace, keep what you know to yourself.

-- Even if you think their diagnosis is uncommon, be polite about it and don't keep your thoughts and opinions to yourself. Don't pretend that you don't know what they're going through or how they feel.
-- You should keep your communications work-related. Your coworker may not want others to stigmatize or pity them.
-- Your policy as a co-worker could change. Be open to anyone and answer any questions they have, without making it personal.
-- If you absolutely must disclose your coworker's mental or physical condition, be discreet and let others know clearly. Expressing any concern for their mental or physical condition will be a recipe for tenating discipline standards in the workplace.
