Difficult people come in all shapes and sizes. Here are some difficult people types:
Their numbers are small, but their impact is large
Difficult to understand
Do not respect boundaries
Immune to all the usual methods of communication and persuasion
Habitual behavior that affects most of the people with who they come in contact
Loss of productivity, absenteeism, and lost customers or clients
Frustrate and demoralize
Accept that they are difficult to deal with and that you cannot change them, but you can change your response to them. Key factor is to respond in ways that are not expected by the difficult person.
