Yes, friend, it should be clear that along with the prescribed qualification, a welfare officer has to attend the State Chief Inspector of Factories for a viva-voce test. In this test, they want to see the knowledge of the regional language, i.e., for Bengal, a welfare officer should know the Bengali language (speak/write/read). They also test the knowledge of labor and welfare laws. There is a slab for recruiting welfare officers in an organization, and in West Bengal, as far as my knowledge goes, it is 01 for 500 to 1000 employees. I myself completed DSW (Diploma in Social Welfare) from Calcutta University in 1999 and started my career as a welfare officer and am presently working as Manager (HR). Thanks to all. rrtpan
