Summarize this article:

When you’re the boss, you have to separate yourself from your employees. While you can still grab lunch or join them for the occasional happy hour, you need to behave professionally the entire time. If employees see you as a peer, you will lose your authority. Don’t overshare personal details, such as what you did over the weekend or the issues you’re having with a relative. Your employees need to see you as a boss, not a friend. Keep your conversations centered on the workplace or your professional experiences. For example, discuss your work goals instead of your personal goals. Spreading gossip will destroy your credibility as a boss immediately. Not only that, but rumors that come out of your mouth instantly sound like truths. Additionally, employees who are the subject of rumors will lose trust in you.

Summary:
Avoid socializing with your employees as you would with coworkers. Maintain strong boundaries around your personal life. Avoid engaging in office gossip.
