New HR Executive in a Startup: How Do I Navigate My Role Without a Mentor?

I am a fresh graduate who has joined as an HR Executive Trainee, and I don't have any superior to guide me. I need help as this is a small-sized start-up company with 20 employees, and I am responsible for recruitment, joining formalities, payroll (manual), attendance, and database maintenance.

Please suggest other activities I can undertake as an HR.

Regards

You may have to consider all the statutory regulations as they play a vital role. Besides that, you can provide counseling to motivate employees, conduct induction programs, training sessions, and focus on their development.
