Unfortunately, you have not mentioned your qualification. Knowing the local language, Hindi and English is fine and will be useful; but if you want to make a career in HR, which is apparently your prime area of interest as a Career, go ahead.
However, it is steep climb. If you are just a graduate, you need solid experience. Go to any good bookstore and buy a standard textbook on Indian labor laws. If you have a background in commerce, you might find it a bit easy. However, after the advent of Google and YouTube, it is very likely that even entire PowerPoint presenatations on the basics of labor laws like the Industrial Disputes Act, 1947, the Factories Act, Workmen ' s compensation Act, Minimum Wages Act and so on are available in Gujarathi itself. Once you know at least the basics, make out a good resume and approach the HR Department of a very small organization employing just two hundred people. Even if they tell you that there is no vacancy, volunteer to work for free as a trainee. Slog it out for over 12 hours. Go to the factory as often as possible to know the pluse of the workers. After office hours, just visit the houses of a few workers to understand their social position. Go through all files in the HR department and take down notes on whatever you get to see. For example, the organization would have an organizational structure and perhaps some vague or sometimes detailed job descriptions for various positions. Please do note that job descriptions is only for the position and not person. Check how many people ideally fit such job descriptions.
Secondly, learn everything from practical experience. For your kind information, there are Government of India and State Government recognized qualifications that are duly mentioned by the State Government in their Gazette, for appointment as Welare Officers under the Factories Act. Go through this document in the minutest detail. Then go on to acquire the best qualification in HR. Ideally, even after three years, I'd your financial position is good, right away take the entrance examination which is always conducted mostly in the English language, for admission into the two famous institutes called XLRI, which is housed at Jamshedpur and the other one called the Tata Institute if Social Sciences, Mumbai. These are the two best, two year full time qualifications.
Thirdly,if you are not able to do that,check with some good HR professionals in Gujarat, what you can do, part-time. Possibly, even the Gujarat University, Ahmedabad, may be having a part-time diploma course in HR. You positively need one post graduate qualification. And note,the correspondence or distance education courses are not worth the paper on which the degree certificate gets printed.
Fourthly, you need to get your hands and your pants dirty in the shop floor and learn at least the basics of how the factory works. Your practical experience in time office management, in administration of welfare amenities, grievance handling, day-to-day interactions with the trade unions, the politics played out in each department and so on, will enable you to get something like an Asst Manager position after six years of experience.
Forthly, the vital experience is in the signing of wage settlements under section 18(1) of the ID Act. This will come to you only after 12 years of experience, when you should jump to a bigger organization having 800 or thousand employees. Obviously, if the unit is just one unit of L&T or say, the Aditya Birla Group, even better. That would offer you a platform for you to learn far better.
Fifthly, you must understand that it pays to get experience in all areas and not just the more glamarious areas like Training and Development, Performance Management, and so on, which are key areas only in the IT sector.
Sixthly, you need to also become very cunning and ruthless. Generally, in factory environments, your role will be to reduce cost left, right and center. You can't have moral values that go directly against such practices. If you try to champion the cause of workmen, you are gone. In a globalized environment, everything is fair in love and war. In organizations across the country, for the next 60 months, it is going to be a big war. It is going to be very tough. The HR department will be used as a tool to all sorts of unethical things. Even in one well known Chennai headquarted IT organization, the HR Managers are asked and mandated to simply force the employees to quit. This is the reality.
Have a solid experience in manufacturing before you go to IT. Please go through one recent article of mine on why HR has still not reached the status of marketing or finance. That will guide you.
All the very best.
