How to deal with harassment by employers

Dear Sir/madam, Me and my husband both are working in banking industry. I am in a nationalised bank while my husband is working in a Regional Rural Bank, my bank followed the guidelines of same station posting.four months ago i.e. in feb 2017 my husband felt ill, he was suffering from swelling in lever and infections so he took medical leave and doctor recommended him bed rest. during sanctioned medical leave sr. manager HRM of regional office called my husband and asked to be physically present in RO immediately to cross check whether he is in the town or not. some how my husband managed to reach in RO and met SR manager HRM. HRM asked for medical treatment documents and reports, my husband gave him all the reports but HRM was not satisfied with this too, further he called Doctor to confirm telephonically and HRM was interrogating that physician too. HE harassed a patient and after one month my husband got transferred. so tell me whether I can take any action against bank's management
