Given its purpose, the aim of the study was to gain insight into the experience of stress in the workplace of the nurses and technicians in the psychiatric hospitals and clinics, to determine the degree of burnout at work and the mismatch between the emotions they experience and the expression of the emotions conditioned by work demands. Perception of the need for the supervision and willingness to engage in the supervision. The research was conducted on a sample of 164 nurses and technicians employed in five psychiatric hospitals and clinics in Croatia. Research results: the nurses and technicians with secondary education assess more stressful hazards and harms in work and shift work, and in total experience more stress compared to the nurses and technicians who have bachelors and masters of nursing. The nurses and technicians aged 24-31 are more exhausted than the colleagues who have 0 to 23 years of service. The differences between the women and men, i.e nurses and technicians, were found in the assessment of the frequency of the emotional compliance, in a way that the women who were assessed more are often emotionally in accordance. The respondents in the age group of 20 to 35 years are assessed as less often emotionally adjusted compared to older respondents in the age group of 52 to 67 years. The respondents aged 36 to 51 were less likely to use emotion in the comparison with younger respondents aged 20 to 35 and older respondents aged 52 to 67. When it comes to the perception of the need for supervision, no differences were found with regard to gender, age and length of service. The respondents with secondary education show less need for supervision compared to more educated colleagues. The women, i.e. nurses, show a greater willingness to be involved in supervision, as do the bachelors and masters of nursing. No differences were found in readiness to engage in supervision with respect to age and seniority.
