Oh, I am sorry! They have not included the labor laws; they might have taken out the course. Regarding MBL, the course is completely related to laws, and to be frank, it hardly has any help for management graduates. The course is good for corporate practitioners of law. In fact, I have completed that course from there. We used to have projects and assignments mandatory. Now, no such practical papers are included with the theory, but I would tell you that it hardly helps for management, labor, or HR. However, Human Rights Law would help you in your aspect since that does include labor stuff both domestic and international.
You may call them up and inquire about the course. If you are interested in any course, you may go ahead and do it. My best wishes.
Labor Management Opportunities
If you are keen on labor management, MSW (Master of Social Welfare) has the best scope.
PGD in Labor Laws
Bangalore University offers the PGD in Labor Laws, a one-year course.
If I remember correctly, there are other institutions mentioned for the PGD in labor laws on this site itself. If you search, it may help you.
