Dear Ms. Ruchi,
Greetings for the day
Exploring HR and Labor Laws
HR encompasses a wide range of concepts, including various statutory laws, labor laws, and concepts related to recruitment, selection, payroll, compliance, etc. If you specifically want to learn about labor laws, I recommend purchasing a Labor & Industrial manual, which will greatly assist you in understanding the various labor laws. TDS, EPF, ESI, and PT are deductions made from income/salary and are just a small part of HR.
If you have information about these, then I suggest you focus on payrolls, as the aforementioned deductions fall under the payroll category.
Regards,
