Leo: Daily green

Here he comes. That arrogant, unfunny, obnoxious coworker who calls you 'chief' and punches your arm. Simplifying your life means detoxifying your environment. You can always go for the temporary fix: headphones or a closed door. But for a long-term solution, communication is your best bet. If that doesn't work, bring it to the next level and talk to hr or your boss.
