The aim of this study was to check differences in the level of stress in people with A and B type personality employed in office jobs, check the representation of A and B personality types among supervisors and their employees and verify the ways of coping with stress commonly used by A and B personality types. The study was conducted online and there was total of 115 participants who were employed in the office occupations (administrative professions, experts for human resources, accounting and financial professions, desk clerks and several mathematical and computer scientists). Jenkins Activity Survey questionnaire was used to test the A and B type personality, COPE questionnaire for assessment of coping skills and stress level was measured with self-assessment question. Results showed no statistically significant difference in the prevalence of people A and B personality types among supervisors and their employees. There is statistically significant difference in level of stress in people with A and B personality type in a way that people with type A personality experience higher level of stress at work. People with A personality type more frequently use problem focused coping and avoiding than B type personality people. Results showed no statistically significant difference in use of emotion focused coping for A and B type personalities. Results showing use of coping strategies do not completely confirm results from previous research so this area needs additional verification.
