Variety of work, but toxic leadership undermines growth - Utilization Management Humana Employee Review

Lots of old retired nurses who refuse to learn and progress with modern capabilities. Leadership just babies them and allows them to do what they want. When you apply for a position, even a leadership one, everyone is told who applied. I applied for the position as the Manager of my team and was told by the Director that I was definitely qualified and would be amazing at the job but it was being given to someone who'd been there longer to "test her out" because she'd been there longer. That person was told I'd applied and she made my life miserable. Suppressing my opportunities for growth and development, refusing to allow me to be trained in all elements of our team's functions so I wouldn't be able to know more than she did. The assistant managers pushed for me to get more opportunities but they were denied. I was the highest performing and had no errors of the team of over 25. Never anything negative in my monthly reviews. Nothing but praise. Ultimately, she started having her own performance issues and turned vindictive towards me. Started denying my PTO requests, passing me over for raises or team promotions, and spreading rumors about my work ethic. I'd been there for over 8 years before she joined the team and was hoping to stay there for at least 8 more. Leadership (Director) over her was unwilling to question what she was saying though they knew me and worked with me directly. I put in my 2 weeks while the supervisor was mysteriously out. The next day, she told me to turn in my computer and not come back. I'm glad I left the toxic environment. Ultimately, she got fired
