Filled grievance to the same Gender

Three days ago, I sent an email to my manager regarding an inappropriate incident at the workplace.

After joining the office, a few days later, one of my colleagues started calling me "Gandhi" because my appearance resembled Gandhi. This was because I had shaved my head after my grandfather passed away.

Gradually, a few others started calling me "Gandhi" and using slangs to tease me. This has been happening for the past 3–4 months. However, I never complained to my supervisor, even though they had previously told me to approach them if I ever felt humiliated. I tolerated this behavior, thinking about their jobs and avoiding any conflicts.

Despite my silence, the harassment continued. One day, one of my team members made caste-based remarks, saying things like, "Your caste does haircuts in Bihar," in front of everyone. I tolerated this again, even though it was deeply humiliating.

The situation escalated when I accompanied them to the ground floor of the office premises. I asked a random question about their current job roles, and in response, one of them hit me in a sensitive area. After this incident, I felt extreme pain and emotional distress.

I returned to my room and immediately filed a complaint with my manager. The next day, HR arranged a meeting to address the issue. I shared the entire story, and HR successfully filed a grievance against the individuals involved.

So in this Case what Acts will impose on them or there are any chance they can defend it. They are from the gender.
