Mental harrassment at workplace

Dear Team,

Need legal advice and guidance with one issue that we are facing at work place.

 We have a colleague who has been harassing us (HR team members) in our office at Mumbai. He is our Admin manager and we are required to work with him and his team on a daily basis. We are being mentally harassed by him with following instances:

·         Not providing adequate support and changing the processes time and again just show that we do not follow processes.

·         Escalating everything, even the smallest of the matters to Head of HR who sits in Chennai office. He does not interact with us in person but only plays mail games.

·         Threatening is indirectly that if we don’t work as per his whims and fancies, he will create enemies for us from within the organization

·         Shouting at junior HR staff and verbally trying to create fear amongst them causing mental stress.

·         Making an office-boy spy at us all the time.

I need to know if we can take any legal action against this person? If so, then please guide on the way ahead.

Note that he does not report to HR Head but to Admin head and admin is a separate function. Many verbal escalations to our boss and his boss has not worked at all. Harassment has increased to a great extent in last few weeks.

Awaiting your guidance. 

Thanking you in advance.

Regards,

Monica
