Inflexible: This type of person will probably be closed-minded and rigid in their approach to new things or anything they don't like or are uncomfortable with. They will not be very interested in accommodating others or adapting their ways of thinking to be like others unless it suits them to do so. They don't like it when the rules change and may drag their feet in making changes to comply with new rules and procedures. In management, their approach may often be characterized as "my way or the highway".
Adaptable: This person will be open minded and flexible in their approach to new ideas or things that are presented to them. They are willing to change their methods and procedures to accommodate others in order to achieve harmony and compatibility. Even if they believe their way is the best way, they are at least open to compromising in order to achieve balance and harmony.
