Your leading role is the most reliable predictor of how you will act and react on a daily basis. Your leading role can also be described as the comfort zone for your personality.
If you are working or fulfilling roles that are congruent with your leading role, there is minimal stress involved. The opposite is also true. If your work requires tasks and playing roles that are not congruent with your leading role, you will feel higher levels of work-related stress.
An example would be the person with a leading role of Analyzer in a position where it was necessary to make snap decisions. Another example would be a leading role of Enterpriser who has to deal with detailed paperwork or slow and bureaucratic processes.
