Retaliation For Filling A Partial Unemployment Claim. Is This Case Lawsuit Worthy?

I came back from vacation and had my hours cut from 32+ to 8 hours a week with less than a week's notice along with a two month notice of termination of health insurance all this when I was 4 months pregnant.

I had a feeling she was just trying to get me to quit because others at the office were telling me I should just quit including two who have made the work place uncomfortable for many via verbal abuse which the owner is aware of and simply lets them continue on with. Recently I filed for partial unemployment and the owner became aware and became increasingly hostile.

Today I had to ask her for a letter that my husband needed for his HR department verifying the end of my health insurance so he can add me to his with no gap in care as I am now 5 months pregnant. She yelled that I didn't need it and that she will fire me if I receive partial unemployment almost as if to scare me into withdrawing my claim. Many people in the office heard this tirade. She also said that she wrote on the unemployment document that I told her that I was going to quit, which I NEVER did.

What did she expect me to do? Plus, there's not a line of employers out the door looking for a pregnant women who is 5 months along!

I feel this, among other things, is making a hostile work environment and she is doing so just to make me quit so she doesn't have to deal with unemployment or fmla and she is willing to knowingly falsify documents in order to do so. I am also afraid she will make things up now to create a paper trail in order to get what she wants which is me, unemployment and disability/fmla out of the picture.

What is my course of action? Do I have a case here?
