Aim – This study investigates the effect of Family-Supportive Supervisor Behaviour (FSSB), work-life balance, job satisfaction, motivation, and job performance among married private employees in Indonesia. Methodology – Data collection was carried out online using Goole form. This study used a sample of 206 private employees who were married and worked for at least 3 years in Indonesia. Data was analysed using Structural Equational Model (SEM) with Lisrel 8.80 software. Findings – The result showed that FSBB, job satisfaction, and motivation, have a positive effect on job performance. FSSB also has a positive effect on motivation. Work-life balance and motivation also positively influence job satisfaction. Another finding showed that work-life balance has no effect on the performance of married private employees. Based on testing the indirect relationship, there are two mediating roles whose results are significant, namely motivation mediates the relationship between FSSB on job performance. In addition, job satisfaction mediates the relationship between motivation and job performance. Limitations – This research still has some limitations that need to be improved in the future. First, the survey only focuses on private sector employees. Second, this study uses respondents who are private employees, married, but limited to a minimum working period of 3 years and a minimum education of bachelor’s degrees. Third, based on regional distribution, most of the respondents work on the island of Java, especially in the Greater Jakarta area. Fourth, the variables used in this study only focus on five variables, namely FSSB, work-life balance, motivation, job satisfaction, and performance. Originality/value – The study contributes to literature that the family-supportive supervisor behaviours can increase motivation and job performance especially for among private employees who are married. When motivation increases, it affects satisfaction and job performance. Companies can also implement a work-life balance as an effort to increase job satisfaction.
