There are no standard SOP for each industry. Much depends upon what kind of retail industry you are talking about. There are a lot of products available in the market and HR will depend upon that kind of business. Even in Retail, marketing and manufacturing are there. Am an HR Consultant with ten years of experience and with additional 40 years experience with work experience, totalling nearly 51 years. You can google my name NK Sundaram and find out. I have clients in India and gulf countries and I do not charge much. I will give you exact input based on research and discussion with you and your management. If interested, please revert.
