My client, a 44 year old teacher, john, is experiencing issues at work. He has been in the teaching field for 15 years, however, he feels unappreciated at work. Of late, john is experiencing conflicts with his spouse and his 17 year old son who has been recently diagnosed with a personality disorder and as a result, he is going through psychiatric assessments. For John’s case, I have decided to apply Donald E. Super and John L. Holland’s theory. The Theory Of Donald E. Super has provided us with great knowledge about how career decisions are made.

The aspect of this theory is that as it seems random diversities in the behaviour in actuality, is rather organized and constant, as a result of fundamental differences in the methods individuals prefer to use in their way of viewing, in other words, perception and judging. Perception involves all the paths of becoming aware of people, things, incidents or ideas. Judgement involves all the ways of arriving to conclusions about what has been perceived. When different people have different perceptions of things and how they reach conclusion, it is only natural that they will have different types of interests, values, reactions, skills and motivations. I decided to use MBTI on john so as to understand his perception and judgemnet of things, for his case his work and family, and also to explain to him specificly what may be best for him keeping in mind that he has to be the one making the ultimate decions and I am here to guide him through.
