Dear Dattatraya,You have raised one liner question but it is difficult to aswer in one line. In brief Labor Law is the body of laws, administrative rulings, and precedents which address the relationship between and among employers, employees, and organizations.When it comes to conduct business operations at the branch offices or head office, it is it is very important to adhere to the statutory regulation as per the state & central act of the resecpective location.
Suggest to spend some time in reading & learning acts like Contract & labour (R&A), Shops & Establishment Act, Minimum Wages Act, Payment & Wages Act, PF Act,ESI Act etc. etc....
