Whether your business is done in person, over the phone, or even by email, a client or customer can sense the connection between the manager and their team. They gauge how fast information is retrieved and how well they work together to get their project done. If you notice a loss in customers, consider what impression you or your manager is portraying to them. If possible, follow up with these lost clients and see what made them take away their business. Was the work inadequate? Is the manager making unnecessary comments? Are demands not being met? If the answer has something to do with how the manager acted or handled the account, speak with the manager right away to correct the situation and prevent the same kind of behavior in the future.
