AssLou's journey

I was terminated from my job last Wednesday after being put on suspension, which was later changed to termination. I signed the termination paperwork on May 20th and received an email the next day about my employee account being deleted. Although I'm no longer employed, the company is pushing for a grievance meeting due to how my termination was handled. I'm considering sending them an email to withdraw from the process, stating that my decision to move on should not be seen as an admission of guilt. My experience there was extremely toxic and, at times, racist. I really want nothing to do with them anymore and I'm unsure if I am required to attend this meeting.
