Mental Harassment at work place

I am an female employee in a private institution affiliated with AICTE. College management has provided me a room in faculty residence for which no legal bond is signed. Now, I am being forced to share my room with a colleague. I can't share the room because of following reasons: 1.I am recently married and my husband & family visits me often. 2.Other person is vegetarian and I am non vegetarian. 3.We both share same college timing, So cooking will be difficult(college timing:9:00-4.30) For 1st point, college management provided a solution to give me guest house every time my family visits.I dont want to make my private life public by asking for guest room on their arrival. I have denied to share my room.But college management is forcing for it..and even saying that,If u cant share,You leave the hostel which I dont because leaving the hostel for me will result me leaving the college and be unemployed. I have completed 2 years working here.And I am at post of assistant professor. Management is harassing me mentally. What legal actions can be taken against them?
