Dear Sonia,
I agree with Kritarth Consulting. Value Addition never be futile.
You are working HR professional. You have one Master degree in your credit. My question is to you, why you wish to pursue another master degree and that too in same stream? Both the PGDM (HR) and MSW degrees are equivalent with more or less similar syllabus to my knowledge.
You really wish to add to your value, do some thing else in cross function. You can do CS. You can do some thing in Information Technology. ISTD is another option. You can also do LL.B. which can be helpful to you in HR position. This is my personal suggestion.
You are in to manufacturing. Go for registration as Welfare Officer if your PGDM (HR) is recognised as qualification for registration as Welfare Officer. All the Best.
