This study aimed to clarify the impact of applying the integrated management system for quality, environment and health on human performance in hotels, by identifying the reality of both human performance and the integrated management system for quality, environment and health in these hotels and the relationship between them. To achieve this, a questionnaire was used, where 150 forms were distributed in 8 hotels that applied the integrated management system for quality, environment and health from a total of 15 (4-5 star hotels) in Alexandria Governorate. The number of retrieved questionnaires valid for statistical analysis reached 125, and after processing the data of these questionnaires using the SPSS, V21 program, the study reached a set of results, the most important of which are: • There is a statistically significant effect at the significance level α≤ 0.05 for the application of the integrated management system for quality, environment and health on human performance in hotels. • There is a statistically significant effect at the significance level α ≤ 0.05 for applying the requirements of the integrated management system for quality, environment and health (policy, planning, implementation, operation, examination and management review) on human performance in hotels. Based on the previous results, the following suggestions were made: • The necessity for hotels to obtain certificates for the new versions of the Quality Management System (ISO 9001: 2015) and the Environmental Management System (ISO 14001: 2015), especially with the issuance of the Occupational Health and Safety Management System specification (ISO 45001: 2018), in order to facilitate the integration between them, as it contains the same structure and the same main requirements. • The necessity of making hotel staff aware of the impact of applying the integrated management system for quality, environment and health on improving the performance of the institution in general and its impact on improving its human performance in particular.
