The modern world creates conditions for the ubiquity of stress in the workplace. Numerous causes, stressors, are accompanied by numerous consequences. The health consequences for the individual lead to harm for the entire organisation. The greater the exposure to stressors, the more severe the consequences. Chronic stress leads to burnout and more serious effects on health and work performance. The nursing profession has always been considered very stressful and demanding. Previous research has indicated that nurses are particularly sensitive to stress and that stress brings particular complications for them as other people are dependent on them.During the last two years, health workers were exposed to even greater stress due to the COVID-19 pandemic. Managing stress and its prevention was already a necessity, officially legislated by the authorities. The pandemic multiplied the stress problem for health workers as a record number of potentially terminally ill patients were admitted in record time. For health workers, this also meant shortages of medicines and space, a record negative patient-to-health worker ratio and various other negative side effects, both social and even political. For all these reasons, a survey was conducted on nurses' perceptions of stress levels during the pandemic. The research was conducted through social media using an online questionnaire between 25/07/2022 and 03/08/2022 and exclusively targeted individuals working as nurses. The work showed that the COVID-19 pandemic has a major impact on the majority of healthcare workers and that almost all of them are aware of the stressful impact of the coronavirus on their health, as well as other consequences of the pandemic on their profession and organisations. At the same time, the results give a negative picture of the impact of stress, but also a positive picture of the informedness and attitudes of health workers towards the problem. The apparent willingness of these health professionals to contemplate about and address the problem of stress bodes well for the effectiveness of education and prevention programmes and stress management techniques. As two years after the first coronavirus case in the Republic of Croatia, work is still underway to find out the actual aetiology of the virus and the disease it causes, and to find an effective drug and vaccine, further education of health workers about stress and its prevention in the workplace is an absolute necessity.
