At first glance, they are funny people who like joking around. They do not hesitate to use humor to lighten up difficult situations. However, that does not mean you should see them as careless and not as serious workers. Managers should treat them with full respect.
You should not think of extroverts in terms of black and white, i.e., "extroverts act first and think later, while introverts think first and then act". Many extroverts excel in planning and creating structures because they like things to be in order. Managers should not believe stereotypes and sweeping statements.
Managers sometimes tend to look for ways to silence extroverts. However, they do not realize that it is not idle chatter, but the way extroverts think and solve problems. Five minutes of conversation with a colleague may be sufficient for an extrovert to come up with a solution which otherwise would have taken him at least an hour. This saves time for everybody.
Monotonous activity kills their creativity. The work and think best when they do not have to sit in one place all day or the whole week. It helps when they can move to another room, to their home office or somewhere else outside the company. It certainly does not mean that they want to avoid work.
The fact that someone is an extrovert does not automatically mean he needs to be around people 24/7 and to constantly be sharing with others. Even extroverts sometimes need to relax in privacy and silence. Try to see your subordinates more as individuals, not just extroverts and introverts. Let them show you who they are and which work suits them best.
