The subject of the final work are changes and stress in the organization. The paper presents the impact of changes on the level of employee stress in the organization. It tries to point out that stress is one of the biggest problems of employees in the workplace and emphasize the importance of prevention, monitoring and finding ways to reduce the level of stress of employees in organizations. Monitoring the level of stress in employees is important because employees who are under stress affect the overall business of the organization. One of the causes of stress in employees is organizational change. Organizational changes, if carefully planned and systematically implemented in business, enable organizations to grow, develop and improve their business. The people responsible for planning, implementing and monitoring organizational change are managers, and how successfully organizational change is implemented in an organization largely depends on its employees. The employees of the organization, when introducing organizational changes, will inevitably be under stress, and it is up to the managers how they will manage the stress level of the employees. The more employees in an organization are under stress more often mistakes will happen, the organizational climate becomes negative, employees become less productive, and interrelationships in the organization become disrupted. In order for organizational changes to have the least possible impact on the level of employee stress, two approaches to stress management in the organization are applied - individual and organizational. Both approaches help employees identify the causes of stress and find ways to reduce stress levels.
