Building a Strong HR Department in Pharma: What Guidelines Should I Follow?

Request for HR Guidelines in the Pharma Industry

Please help with the rules and regulations to be followed in the pharma industry. In my organization, we have more employees in sales than in HR, accounting, and logistics. Kindly advise on the rules I need to follow for establishing a strong HR department.

Thank you.

Organization is following travel and leave policies, but I want to know what rules I have to add or create in the policies so that it will be good for the organization. What strategies should be made for sales employees for enhancing sales and their motivation? Please help me.
