Assistant Manager not sure what to do...

[Bnkrbv]

I have been with this Huge Bank in CA going on 15 years. I was diagnosed with Lupus in March after several ear infections and a butterfly rash on my face. I was up front with my boss of what was going on and even gave her info on what to expect with this chronic disease. April I got sick again with bronchitis and had to be off for more time with bad shortness of breath thinking I was going to die. I came back to a complete nightmare. She took away my scheduling, time sheet approval & started banning me from all my managerial rights. In May my top teller was injured right before she was going to transfer to AZ. My manager bashed her name and band her from transferring based on lies. When I tried to stick up for her I started getting harassed even more. The manager had the higher up market manager brain washed. I kept my composure and continued to go on. In July my manager took it upon herself to cash a vary large check payable to a Corporation before her vacation (which for anyone is not allowed). The teller came to me saying she was afraid of loosing her job & when I learned why & what had happened I felt it had to be reported to higher up. I did what was right & reported it only to be interrogated 3xs as long as she was & told I didn't do my job right because I should've told her what she did wrong & had her return the money??? They did nothing to her for her actions and literally caused me to have a mental break down. My tellers involved also had medical issues as a result of her & higher up actions and now we have a Lawyer representing us but are scared of the whole nightmare & what will be the final results of it??? Someone please help with advise / feedback to this shortened version of our nightmare!!!
