@ Deepali,
As per my knowledge following things needs to be displayed on office notice board.
1) Registration Certificate of Shops & Establishment.
2) Licence obtained under Contract Labour (Regulation & Abolition) Act, 1970. (if any one employed in terms of contract labour)
3) Abstract of Minimum Wages Act, 1948.
4) Holiday List for current Calender Year.
5) Any notices given to company by Government authorities.
As such people are not following it but its advisable to display above things on premise from where Company operates.
I hope this will help.
