Lets presume that its a group of 10 members:
1. What they are - Designations, Grade, Salary scale, Reporting structure. (Pay Policy)
2. What they do - JD's of all the members and if possible KPI's too
3. When they do - Working Days, Fixed working hours, Flexi Hours, Work from Home
4. What Benefits they get - Incentive Policy, Leave Policy (EL/ CL/SL), Maternity Policy
As the company grow you may go with IT policy, Employee engagement, Perks (Joining Bonus, retainer ship bonus), ESOP's for Sr. Profiles etc.
