Getting fired this week

I am a candidate accuring fieldwork hours at a company, and i believe that I will be fired this week. What can I do to ensure that I have access to my hours/ and have proper documentation? I've been tracking with ripley and getting a monthly form signed each month and I have pdfs for each month on my personal computer. My direct supervisor is a micromanager, and interpersonally we do not get along. I made attempts to repair the situation and I instigated mediation between her and I to no solution with hr present. I believe the company is attempting to create a paper trail to fire me "with cause" when I feel like her behavior has been inhibiting me from doing my job. This is a little bit of a ramble, but if anyone has been in my situation or something similar, please send me a dm.... I would really appreciate it.
