Management pretends to care to save face, but will do everything in their power to push out those they feel threatened by or isn't in their "club". If you try to actually address real concerns, they do not do anything about it unless it ruins the company's reputation.
I loved working here before but your manager will dictate how your career will go. Even if they lie on you, it doesn't matter and there is a secret "black-balled" list for some former employees. As a recruiter, I used to see former employees who were technically still eligible for rehire - but hiring managers would seek out what was your reputation from others despite your qualifications. Of course, I know they want to ensure a great hire, but at least give them the chance to interview if their qualifications meet the job description. I've even worked with managers that told me to make sure to let other HMs of other role not hire their former employee - which is not fair or ethical. Sometimes, the rules and best practices aren't followed despite us legally saying it is.
