The purpose of this study is to explore the impact of employee development, represented by training and promotion, osn growth mindset, empowerment, job security and turnover intention among workers in the Indonesian garment industry. A survey was conducted using 2,580 participants who work in the Indonesian garment industry. The data was analysed using a Structural Equation Model (SEM) with Lisrel 8.8. The results indicated that employee development had a positive impact on workers' growth mindset and empowerment, which could lead to a decrease in turnover intention among workers in the garment industry. This study also found that employee job security had a negative impact on turnover intention. And finally, it was found that employee development was unable to increase and or reduce job security perceived by employees.
