Please do note that you have only two excellent institutes for the best Post Graduate Qualification in HR. The two superb institutes that offer the Post Graduate Degree Course in Personnel Management and Industrial Relations are the Xavier Labor Relations Institute, Jamshedpur, and the Tata Institute of Social Sciences, Mumbai. Both have their own written examinations, followed by Group Discussion and interview. You have not mentioned the percentage of marks in your Graduate examination. However, please do note that these institutes normally expect you to have scored more than 55% in the total aggregate in the first attempt without any arrears.
The written examination is tough. You can go through the websites of these institutes to get an idea. Apart from these there are some good institutes where you will get what is called the Master's Degree in Social Work, with a specialization in HR. This is a full time two years program. If you do not get a seat in TISS or XLRI, you can join one of these institutions.
Quite apart from these, please do note. None of the distance education programs offered by many Universities or Deemed Universities are recognized by the industry. Some organizations recognize the Post Graduate Diploma in Personnel Management, which is offered as an external course by the National Institute of Personnel Management (NIPM) which is recognized by the Government of India, and the AICTE. However, please do note that the examinations are very tough and you need to put in so many hours of hard work to pass the examination.
If you are very serious in HR, these are the routes. Otherwise, you need to continue in your job, and try for a junior level job in HR. If you get it, grab it and then grow through experience. In the meanwhile, try to find out if there is a Part time course which can be considered as equivalent to the MSW or MBA degree for the appointment of welfare officers under the Factories Act.
Since I do not know where you are based, I cannot offer you specific details in this regard. However, I can guide you further. If there is a branch of what is called the National Productivity Council in your city, check if they run the Part-time PG Diploma course. This should be recognized by your State Government. Please do note that there are some part time PGDM institutes in big cities. They offer the PGDM course with a HR specialization.
You seem to be interested in HR in BPO/IT organizations. Please do note that there is huge competition here too. The professionals go through the hard grind and unless you have some exposure in what is called Industrial Relations, in the manufacturing industry, you cannot get a good grasp of the complex IT labor, which is a class by itself. Though there is no trade Union, the complexities of HR in IT industry are huge. There will be so many situations where you need to understand the nitty gritty of all inter-personal relations and exposure in a manufacturing environment will teach several tricks that will help you to mold your career in IT. Please do note that this is a must.
Much will depend on what you want to do now, and the route that you want to take. All the very best.
Please do note, to reach up to the level of Manager, you need at least eight years of experience in all aspects of HR.
