great sir. valuable information. I am a new General Manager wanting to setup a HR Dept in my manufacturing company. this will help me a lot.
kindly let me know how many people are required to be there in a HR Dept. for these activities and normally how is the total manpower related to the total HR Dept. people.
please advise.

Dear Mr. KVK,
Thank you so much for your kind appreciation.
Regarding your query... Total no. of head counts required in HR Dept.
Please note, without knowing Manufacturing Process, Current available headcount (on-roll and off-roll), Structure for present manpower, Current available vendors / partners for HR process, Status of compliance's and IR, etc.. etc.. etc. it is not possible for me or any learned members to advice required headcounts in HR department.
Further, you may take help from any professional consultant in your area to set-up HR dept. and identify exact no. of head counts required in your factory / establishment.

Dear colleague,
HR set up and number of HR professionals required depends on industry, type of business, technology employed in mfg process, shift working , all india setup or only in one state etc. which is not given by you.
If you provide this information, then only some meaningful value addition is possible.
