@nidhishah: Perfectly answered.
I too moved into an HR role from being an ES to a VPHR and didn't know what to do with the 35 employees that I had to fit in. In fact, you can start by speaking to employees, and you will surely find your way. There are various aspects to consider such as attendance, leaves, payroll, holidays, late comings, company profile, understanding employee psyche and their expectations, group dynamics, favoritism, office politics, and individuals' positions within the organization before diving into policy and procedure implementation. Listen to employees and understand them; then analyze your way through. Give yourself some time, and you will find yourself amidst controversies, resentment, opposition, and then gradually gain acceptance and agreement. Eventually, you can progress to leadership and exert authority in HR.
