My department is in denial - Mail Sorter Conduent Employee Review

My management is telling me that portions of my employment manual are not real. When you start to succeed in the job, they raise the bar and lower your pay to minimum wage "just because we can". There is ABSOLUTELY ZERO reward in the job. Just be thankful when they use the smaller whip. You are publicly embarrassed and supervisors and managers care more about their machinery than their people. They lie about PTO, sick days, vacation days.. PTO is all they have, but the manual says different. Huge favoritism. New job postings are never mentioned or posted, but quietly mentioned to who they want. It's easier to sue the company with a class action than to get 5 minutes of an upper level managers time. They physically break their mail sorters, then at will them with no chance at unemployment benefits. Management is arrogant and consider themselves 'untouchable' by the law and top management. "Don't waste your time. Many people have tried in the past and nothing came of it". Everything is piece rate so taking a break COSTS you money.
