The study explored how employees' perception of organizational politics influences job insecurity and the role of authentic leadership in moderating this relationship. The study model was established and tested using 474 responses from five-star hotels (26 hotels) and travel agencies (65 travel agency) in Egypt's Greater Cairo area using the PLS-SEM approach. Results revealed that employees' perception of organizational politics positively influences job insecurity; authentic leadership negatively influences the perception of organizational politics and job insecurity and negatively moderates the relationship between organizational politics and job insecurity. The study offers comprehensive theoretical and practical insights into organizational politics in the Egyptian hospitality and tourism sector. It also emphasizes the role of authentic leadership in fostering workplace social exchange and enhancing employees' sense of job security. Hospitality and tourism organizations can create a culture of trust and security, effectively mitigating the negative effects of perception of organizational politics on employee well-being and job security. This ultimately leads to a more engaged, productive, and thriving workforce, contributing to both individual and organizational success.
