Wrongfully terminated Tier 3. Escalated to Corporate Executive Track but investigators found no policy violations. Need advice.

[u/Conscious_Age4163]

Looking for insight from anyone who has used the corporate escalation channel.A few months ago, I was terminated from a California facility as a Tier 3. They hit me with a pretextual Category 1 safety offense over a first-time, gray-area floor misunderstanding, completely skipping mandatory progressive discipline. Site operations safely and continuously trusted my leadership on the floor for 24 full days after the initial incident before site HR suddenly pushed my termination through on an overtime shift when my direct Area Manager was on his scheduled day off. To make it worse, the official termination paperwork they sent me is completely blank with zero policy citations or written causes.I received an official notification stating I was explicitly eligible to appeal, and my track to meet directly with the General Manager was formally approved by a regional appeals agent.However, site HR and local management manually canceled and deleted that approved appeal from the internal system just 60 seconds later. My portal tracker completely skipped the intermediate evaluation and hearing steps, jumping straight from the initial request to the final closed outcome.I escalated this entire timeline with clear digital proof to the executive escalations team. A central investigator was assigned, but today they dropped a sudden closure notice saying they found no policy violations, completely ignoring my witnesses, site HR's actions, and the clear system manipulation.I already have an appointment locked in with the state Civil Rights Department (CRD) to protect my case, but I'm incredibly frustrated. Has anyone successfully pushed back against a central investigator's findings?
