Personality differences of IT professionals and their consequences

[Context] We find ourselves in a time when the IT sector is experiencing a severe shortage of workers, so companies are facing a difficult task - getting the right people to the right jobs as well as keeping them. Motivation plays a big role in this, along with the personality differences between individual IT workers. This thesis aims to characterize specific differences in the personalities of IT professionals and examine their implications in terms of their motivation and other aspects. The theoretical part first discusses the definition of personality psychology concepts. It then focuses on the Big Five personality model, which was used, and the Self-determination framework of work motivation, which represents the chosen theory of motivation. The issue of employer switching frequency is also addressed. In the practical part, hypotheses are formulated and then tested, leading to the fulfillment of the thesis objective. The possible correlation of specific personality dimensions with the studied aspects, i.e. motivation is investigated. The research is carried out using a quantitative method - a questionnaire survey among IT professionals in the Czech Republic. The obtained data are subjected to processing and statistical analysis, leading to their interpretation in accordance with the stated aim of the thesis. Finally, the results of the research are summarized, i.e. especially the observed relationships with statistical significance, which were formulated in the hypotheses and research questions.
