Dear friends,
Of course, I'm delayed by over 9 yrs but still I wish to share some info with you people. There is no hard and fast rule released by private companies as a whole. And if so, they cannot over rule Acts & regulations implemented by the state & central govts. While saying, I presume, your query says 'all' rules & regulations which is impossible to be deliberated here. Since you have raised in citeHR forum I restrict myself to rules & regulations relevant to HR matters.
Govts. enacted two sets of Acts/rules which 1) applicable for govt.employees and 2) applicable for others i.e. quasi-govt. & private sector employees. Indian labour law refers to laws regulating administration of labourers related issues in India. Traditionally, Indian governments at federal and state level have sought to ensure a high degree of protection for workers, but in practice, form of government and because labour is a subject in the concurrent list (both central & state govts.) of the Indian Constitution. These acts & rules are issued subject wise such as Acts meant to cover-
1) Wages to employees- Payment of Wages Act, Minimum Wages Act etc.
2) Governing other benefits payable to employees-Employees Provident Funds, Employees Pension Fund, EDLI, Bonus Act, Gratuity Act, Employees Compensation Act, ESIC etc.
3) Other regulations & Welfare- Maternity Benefit Act, Contract Labour Regulation & Abolition Act, Mines Act, Factories Act, Industrial Disputes Act etc.
4) Taxation matters - Income Tax Act (incl.Capital Gains), Profession Act,
There is diff.between Acts/Rules & Regulations-Acts are covering various definitions, applicability, authorised officials, penalties/fines, filing of statutory returns etc. Whereas Rules & Regulations are made under the pertinent Acts to facilitate administration of provisions of the Act.
No rules & regulations & guidelines, circulars cannot overrule or contradict the provisions contained in the Acts & Rules made thereunder. A list of Acts & Rules (not everything but major acts) is attached for handy ref.
These info.are not up-to-date therefore you have to read with any amendments & updates to have latest info.
