Hi Soujanya,
Congratulations on starting up the same.
In my opinion, a few things are to be taken care of in the beginning:
1. You should start with preparing the HR manual for the company. If it is not there, or else just read carefully the things mentioned in it. If it needs to be revised, then go ahead carefully.
2. For starting anything in HR, in my opinion, one should have the complete employee demographics for the existing employees. If recruiting new, then you can start with some formats such as candidate's info, appointment letter, induction, training, etc., which you can put in one place and start off.
3. Go for some recruitment agencies, job portals, newspaper ads, campaigning in colleges, etc. Also, you should have complete knowledge of the working profile of the staff.
4. Take care of things like performance appraisal, increment, demotion, appreciation, etc., later on.
5. As far as exit is concerned, you can conduct an exit interview. For FFS (Full & final settlements), look for their dues on both parties, take back the company belongings (I-card, Laptop, mobile, etc.) with the issuance of proper NOC, relieving letter, experience certificates, etc.
As far as templates are concerned, I'm sorry I can't help this time. 😢
I hope this will prove to be quite helpful to you, though it is a vast field and we cannot say this is the end!!!
Goodbye with all the best wishes. 😊
