Hello George,
On completion of MSW itself you are fit enough for running a HR/personnel department. If you want to do further studies you can do DPM in National Institute of personnel Management, calcutta or Diploma in Labour Laws from Annamalai University or Madurai Kamaraj University through Distance education.
Hope this helps.
Good Luck.
