Let’s face it, humans are social creatures: We’re bound to develop relationships at our offices. Just remember that in this situation there’s a heightened risk of cat fights, so fraternize with caution. If you’re able to make a long-lasting friend at work, more power to you. And if that friend works in a different department, even better. You’ll still have plenty of stories to share when you have that post-5:00 margarita.
