I'm glad that you liked my "7 Stars of HR" and are interested in knowing and working on them. To learn about them and for implementation, you need to do your work on your own, but I can only give you direction. I understand your situation, your concerns, and what you are feeling about your present situation and career. If you really want to know more about HR and its functions, you need to spend as much time as possible on CiteHR and other HR professional sites to gain knowledge about HRM.
For statutory compliance, you can visit
https://www.citehr.com/93257-what-st...ompliance.html where you will find complete details, requirements, and procedures.
Performance Appraisal
If you want to know about performance appraisal, you can find details and procedures by using the search function. I also suggest you go through my old posts where I have discussed this topic several times with members of CiteHR.
Learning About ESIC & EPF
If you want to learn more about ESIC & EPF, I recommend visiting their official websites first to understand the rules and regulations, forms used, such as Register of Employee and Employer, Claim and Application forms, Challans forms, and Returns. You can visit [ESI Corporation, Chennai](http://esichennai.org) for more information. For sample sheets, calculations, and examples of work, you can find them on this site through the links provided by members for practical understanding.
But the most important thing is that all this is worthless until you put in your own efforts.
Best of Luck
