Way To Start As HR In A Firm

Hi,
I am a fresh PGDM-HR graduate and recently appointed as a HR in a small firm of workforce of 20 people only. The company never had an HR before and so there is no one to guide me for start-up. Please help me what initial steps I can take to understand the company, employees and other activities must do as an HR.
Please help me asap coz I have already wasted 2 days and no clue where to go.
Thanks,
Navneet

Dear Navneet,
Even I am new in this industry and have faced the similar problems.
You can start with small things just to understand how the management is reacting to the changes. You can initiate the dress code policy, office hours and lunch timings, daily attendance records, notice board for uploading some motivational and inspiring quotes, birthday greetings for all the employees through mails and notice board, introduction mails for new joinees, corporate profile which can give a brief idea about the company to the new joinees, etc.
Based on these activities you can find out the receptiveness of your management and accordingly you can work on induction programmes, hierarchy levels, KRAs, JDs for every level in the department, celebrations (either on small or large scale), etc.

Navneet,
There is a ton of stuff already posted here on CiteHR by other members about setting up HR departments etc.
You will also find a ton of stuff about HR Handbooks which will also give you many clues as to what you need to set up and organise.
Please use the reSearch Box at the top of every page. There is a wealth of material here on almost every aspect of HR. Please make good use of the material here to assist you with your HR career.
