In this research, the Servperf method is used to analyze the quality of health and safety services. The main purpose of this article is to determine the quality level of preventive health and safety services provided in the workplaces within the framework of the perception of the employees who benefit from these services. The questionnaire prepared in accordance with the Servperf method was applied to 412 employees working in various sectors, and the results were classified according to age, gender, education level, sector, and the way of providing (internal & external) services. Descriptive statistics were used in the evaluation of results. The total perceived Servperf score of the health and safety services was 2.84, medium level. As the age and education level of the employees increases, the satisfaction level and Servperf scores of the service quality decrease. The satisfaction score of the construction workers is significantly lower than the other sectors. Satisfaction levels of employees in the workplaces where services are provided internally are higher than those of the workplaces offering external sources. Despite legal regulations related to preventive health and safety services, accidents have not decreased in Turkey. The quality of the service provided by external health and safety units is significantly low. Competition arising from the marketization of occupational health and safety services reduces the quality of the service provided. For these reasons, the number of research aimed at determining the quality of these services should be increased both in Turkey and in the world.
