QOne of the people on my team isn't friendly. His work is fine and he does well with clients, but doesn't mix much with the rest of us. I'm trying to build a positive culture, plus it's more fun when people get along. What should I do?
ADetermine if there's a problem; if not, accept that people differ in what they're looking for in the workplace.
The inner game
First, look objectively at your employee's behavior. There's a big difference between reserved and unfriendly, so clarify the situation while setting aside your emotions. List specific behaviors; then, imagine what his version of the same events would be, and how a third party might see them. Also assess whether this is new, or if it's been this way since he was hired. This will help determine if you're reacting to style differences, or if there's a personnel situation to address.
Then evaluate the actual effect his demeanor has. Apart from bothering you, have you had complaints or comments from other employees? If not, this might not be a team issue.
Think about your vision of a positive workplace, from practical aspects related to getting the work done, as well as the ideal team interactions. Try envisioning a week of the "perfect" workplace. What would it look like and sound like? What do people do during lunch hours and break times? Are there after-work get-togethers?
Finally, look at your own bottom line on the situation: "If he doesn't start interacting more, I will ...." Fire him? Accept his strengths and that he's not going to be part of the social scene? Try new ways to understand and engage him?
