Can Ibe fired from my job if I have a pending workers comp law suit.?

I am suing my employer who won't accept my workers comp claim. Now I feel he is retaliating against me since it looks like he may have no choice but to accept the claim. he is using my mental health to say I'm not doing my job and says my current job is creating a conflict of interest for the company since I oversee workers comp for the company. he has made disparaging comments to me in front of other co workers which leads me to believe I'm being railroaded.
