Abstract

The rapid growth of startups in Medan City offers significant opportunities for Generation Z to enter the workforce. However, many startups face challenges in optimizing performance due to limited understanding of Gen Z’s unique work styles and preferences. This study examines the influence of Gen Z’s work style and preferences on performance, with organizational culture as a moderating variable, using a quantitative approach through Partial Least Square Structural Equation Modeling (PLS-SEM). The study surveyed 160 Gen Z employees from various startups in Medan. Results show that work style positively and significantly impacts performance. A flexible, collaborative, and tech-oriented approach enhances task completion. Preferences such as work-life balance, technology use, learning opportunities, and meaningful work also improve performance by increasing engagement and productivity. Moderation analysis reveals that organizational culture negatively moderates the effect of work style on performance—rigid, procedural cultures reduce the benefits of supportive work styles. Conversely, organizational culture positively moderates the influence of preferences on performance. Cultures that value flexibility, collaboration, and innovation strengthen the impact of Gen Z’s preferences. This research supports the Person-Environment Fit and Self-Determination Theory, offering practical insights for startup leaders. Aligning organizational culture and work styles with the values of Generation Z can enhance performance, productivity, and long-term success in the digital era.

Abstract

This study aims to analyze employee performance at Bank BNI by using work environment variables and compensation as independent variables and work motivation as an intervening variable to analyze the effect of employee motivation levels. The sampling technique of this study used purposive sampling which amounted to 100 employees. Data collected using a questionnaire method through Google Form. The data analysis technique in this study was carried out using SmartPLS. The results showed that the work environment has no significant effect on employee performance while compensation and motivation have a significant effect on employee performance. In addition, the work environment has a significant effect on work motivation but compensation has no significant effect on work motivation. The work environment has no significant effect on employee performance through work motivation. However, compensation has a significant effect on employee performance through work motivation. The limitation of this research is that it only uses BNI BANK and with limited respondents. Further research is recommended to expand the research area by using several BANKs and also adding respondents and other variables related to employee performance so that it will produce even better research.
