This study aims to examine the influence of workplace happiness on intention to leave with employee engagement as a mediating variable among full-time Gen Z and millennial employees in consulting firms in Jakarta. A quantitative approach was employed through an online survey questionnaire. Data were collected from 220 respondents and analyzed using SPSS software for linear regression and Sobel Test for mediation test. The results indicate that workplace happiness has a significant negative effect on intention to leave and a positive effect on employee engagement. Additionally, employee engagement partially mediates the relationship between workplace happiness and intention to leave. These findings suggest managerial implications for consulting firms to enhance workplace happiness and employee engagement to reduce intention to leave, particularly among younger generations who have distinct expectations from their work compared to previous generations.
