Dear Mr. Vinod,
Regarding the quarry:
Step 1: You should prepare the list of employees' particulars. According to the date of joining, you allot an employment number to them. It should be a statement managed in an Excel sheet, like serial number/employee number/name/designation/date of joining/father's name/number of years of previous service/educational qualifications, etc.
Step 2: Update all statutory records.
Step 3: If PF/ESI coverage is issued, provide declaration formats to each employee (in duplicate).
Step 4: Create an HR policy and submit it to your management.
Regards, PBS KUMAR
