I was let go after bereavement for no cause

Hi I was “let go” after returning from bereavement with a “it just wasn’t working out”. The company was just bought out 1 1/2 months after I got hired. I was thrown into the position with ZERO training. Possibly because owners that hired me was already out the door. I go on bereavement 3 weeks later and the day I return I am let go. I just passed my 60 day probation period by a few weeks. Let me add i knew it already wasn’t working out for me. I was constantly harassed by another employee and have email documentation of her undermining my authority as a manager (in a another department not hers). My new supervisor (CEO) failed to spend any 1 on 1 time with me and even knowing the lack of company training I received was able to determine that I wasn’t a good fit. I was always the last one to leave and worked through my lunch breaks. Can I sue for wrongful termination? Or for hostile work environment? They didn’t have a reason and said they were already planning to let me go than the bereavement occurred.
