Hello Jyoti,
I always tell my fellow colleagues to do the basics correctly. "Employee Retention Process" starts from the interview. Your communication policy, career planning, transparency in performance appraisal, succession planning, work environment, medical benefits, and retirement benefits. Ensure these things, and I am sure that you will be able to control the attrition rate. You will get good data from your "Employee Satisfaction Survey" and "Exit Interview Details."
These are the things that help a lot in retaining people in any industry. You can also refer to the article "Employee Retention Process and Your Marriage" (Link to the article: [link outdated-removed] riage&id=368554).
I hope this will help. Feel free to ask any query.
Regards,
Sanjeev Sharma
