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 or 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 "their way or the highway".
