In recent years, the concept of an organizational culture in hotels has held an important position on both a theoretical and practical level because this culture significantly affects organizational performance and the strategies adopted by hotels. Therefore, it is considered one of the key factors in determining hotels’ tendency towards outsourcing and sustainable performance. In this study, we aim to analyze the impact of the organizational culture on the level of outsourcing and sustainable performance. To do so, we will use the Competing Values Framework (CVF), which divides organizational culture into four typologies: hierarchical, group, rational, and development cultures. A personal questionnaire was administered to the directors or managers of 114 hotels located in two Egyptian cities: Hurgada and Sharm El Sheikh. The results of the structural model suggest the negative impact of the hierarchical and development cultures on the level of outsourcing. The results show a positive influence of the four types of organizational culture on sustainable performance, suggesting that these hotels have a strong interest in sustainability and the environment. The findings reveal a negative relationship between the level of outsourcing and sustainable performance. Finally, this study presents academic and practical implications, as well as recommendations for future research.
