The results indicate that organizational culture, compensation, and the work environment have a positive effect on performance, while job stress has a negative impact, especially during the pandemic. Motivation, discipline, and work-life balance factors also strengthen the relationship between working conditions and performance. Overall, improving hotel employee performance requires an integrated approach that encompasses psychological, structural, and social factors in the work environment.

The shift toward hybrid work systems has positioned flexible working arrangements as a central strategy in modern organizational design. This study examines how Flexible Working Arrangements influence Employee Performance within a hybrid work context through the mediating role of Organizational and Technological Resources. A quantitative explanatory approach was employed using survey data collected from employees who had experienced hybrid work for at least six months. The data were analyzed using SEM-PLS to test the relationships among flexibility, resources, and performance. The results indicate that Flexible Working Arrangements have a positive and significant direct effect on Employee Performance and a stronger effect on Organizational and Technological Resources, which in turn significantly improve performance. The mediation analysis confirms that resources partially mediate the relationship between flexibility and performance. These findings suggest that autonomy, work–life balance, and engagement derived from flexible working contribute to improved task, contextual, and adaptive performance, but the effectiveness of flexibility depends heavily on supportive organizational practices and technological readiness. The study concludes that performance gains in hybrid systems are achieved when flexible policies are embedded within a resource-supported work environment.

The Work Environment variable has a significant value of 0.024 < 0.05, indicating that Work Environment significantly influences Employee Performance, so the fourth hypothesis (H4) is accepted. The correlation coefficient (R) is 0.955, meaning there is a very strong relationship between the independent and dependent variables. The coefficient of determination (Adjusted R Square) is 0.902 (90.2%), meaning that 90.2% of the variations in Employee Performance are explained by the independent variables, while the remaining 9.8% is influenced by other variables not examined in this study.

Changes in the work landscape due to technological developments and modern organizational dynamics have encouraged the adoption of Flexible Working Arrangements as a human resource management strategy. This study aims to analyze the implementation of Flexible Working Arrangements and their impact on employee engagement and productivity. A qualitative approach with a case study design was used to gain an in-depth understanding of the experiences, perceptions, and meanings constructed by employees and management. Data collection was conducted through in-depth interviews, non-participatory observation, and documentation studies in organizations that have implemented flexible work practices on an ongoing basis. Data analysis was conducted thematically to identify patterns and relationships between phenomena. The results indicate that Flexible Working Arrangements encourage a paradigm shift from attendance-based supervision to results-based performance assessment. Work flexibility contributes positively to employee engagement by increasing autonomy, trust, and psychological well-being, although engagement levels are not uniform across all employees. Employee productivity tends to increase, particularly in jobs that require independence, time efficiency, and individual focus, while coordination challenges remain in teamwork. These findings confirm that Flexible Working Arrangements function optimally when integrated with adaptive leadership, a clear evaluation system, and consistent organizational support. This study provides theoretical and practical contributions to the development of sustainable flexible work policies
