Demand my job back due to wrongful termination

I was terminated by Stripe's because of a team member doing a unauthorized background check on me. I have been at Stripes for two years and I have no secrets. I told them about my conviction in 1991. I was being bullied and harassed by this team member who wanted to work my shift and she went about it this way by going into my background in which Stripe's was already in full knowledge of.
