I only believe in setting HR with three basic HR functions:
1. Statutory
Statutory is the function that takes care of PF, ESI, and all regulatory requirements. This includes the documentation needed for external audits as well.
2. Administration
Administration caters to the entire facility management, from washrooms to the cafeteria, providing all services required by the employees.
3. Strategic
Strategic focuses on policy generation, establishing standards, talent acquisition, training & development, and all strategic functions of HR.
