In addition, “non-legislative provisions” such as the European Framework Agreement on Work-related Stress and the European Framework Agreement on Harassment and Violence at Work, are characterized by generalities and ambiguities that can be interpreted variously. Articles 5 of the Framework Agreement on Work-related Stress states that employers are obligated to protect their employees from work-related problems by adhering to appropriate collective and individual health and safety measures. However, there is no reference on specific techniques and methods that an employer should adopt for the evaluation and resolution of problems associated with work-related stress.
