8. Play nicely with your coworkers.
When you’re working with the same group of people for 40 hours a week, you’re undoubtedly going to make a few friends. Fostering good relationships with your coworkers is great. Not only do you create a more productive and enjoyable atmosphere, but you also prove to your boss that you can effectively communicate with a diverse group of people. So go ahead, bust out the nicknames—as long as they’re all in good fun, of course.
