Hi,
You can try all of these and more
1. Get inputs on corporate vision, HR plan, strategies and policies from your investors, put it in black and white and go for approval
2. Get approval for Annual HR Budget (board may ask you to submit a plan, then you need to have a thorough understanding on all aspects of the department- you can request for 2/3 weeks time)
3. Based on the budget you need to plan your activities; also there will be questions like (should I hire couple of HR folks or should I manage the entire HR department activities with the help of HRMS etc.)
4. HR head would be responsible for certain forms and returns with regard to employee laws (national as well as local)(get everything verified by labor law experts) and keep track of these returns (high priority)
5. Employee bonds and agreements (get everything verified by legal experts)
6. Prepare list of tasks (annual,quarterly and monthly) and schedule tasks
7. Learn the existing HR processes and identify non-value adding elements and suggest for HR Process streamlining
8. Maintain good relationship with all employees and try to learn the employee satisfaction levels, develop channels for informal employee information
9. Evaluate yourself on a weekly basis against the accomplishment of your tasks (you may use MS Projects or Google Docs)
10. Plan and track quality and certification initiatives ( ISO, CMMI,PCMM, Six Sigma etc) based on corporate plan
11. Plan and facilitate Performance Management process and communicate in a systematic manner to top management for necessary action, budget allocation for training etc
12. Monitor employee attrition, exit activities and closely evaluate people and processes associated with
