Using the Slovin formula with a tolerance of 5%, the number of samples was 194 respondents.The results showed that: Organization identification has a significant effect on Voluntary involved in the work;  Internalization at work has a significant effect on Employee loyalty, and Employee job performance; Voluntary involved in work has an insignificant effect on Employee loyalty, and has a significant effect on Employee job performance;  Employee loyalty has a significant effect on Employee job performance. Given that the voluntary variables involved in work have not played a role in employee loyalty, it is recommended that management always increases the feeling of voluntary involvement in the work of employees by more intensively carrying out tasks, and giving their time without expecting rewards. Employees are selfless, and perform their duties for the common good. Likes to help others who need help. Thus, it is hoped that the feeling of voluntary involvement in the work of employees will increase, which in turn will have an impact on increasing employee loyalty.
