Everyone wants to be liked, but in the course of doing business, maintaining likability can be tough. You want to make sure your team works hard toward their goals, and sometimes that means being stern, especially if one or more team members are being insubordinate. But toxic supervisory behaviors result in low morale and increased turnover.
Success in a professional environment requires a delicate balance. Showing assertiveness and self-confidence is a plus, but if you push too far, you could alienate the people you work with every day. The key is to have the self-confidence necessary to navigate the business landscape while still working well with teammates and clients.
