Social norms are one of the best ways to make employees loyal, as well as motivated, and thus to boost the company's productivity. This may seem like an easy task but the truth is that it requires consistency across all the interactions with the employees. The goal of the current study is to determine how social norms affect employee loyalty in the tourism and hospitality businesses. To obtain quantitative data for the study, questionnaires were delivered to staff in Cairo's class (A) travel agencies and five-star hotels. To validate the hypotheses and interpret the acquired data, statistical analysis is utilized. The findings showed that employee happiness had a significant impact on employee loyalty, employee trust enhanced employee loyalty significantly and employee satisfaction rises as a result of leadership support.
