I have faced this a few times. Firstly I would say who is causing harassment. If its a colleague in your team then maybe a conversation with your manager can have a positive effect. If its your manager then try getting in touch with their manager and explain the situation. If its higher up the chain, director, cto/ceo level, people that can't be fired or disciplined easily then I'd say just give up and find new job. Your mental health and well being are more important.
