worst employee experience of my career - Manager Corporate Office TD Employee Review

My team was re-organized 4 times in one year and had 4 different managers. I never received performance feedback, 1 on 1 meetings were used to update managers, communication was one way. Management levels were not consistent, I had a dozen reports in various locations in Canada and US, including managers, with a great deal of responsibility although there were many Senior Managers in my department that had no reports and were in less responsible roles, it didn't make sense. Management lots outside before promoting from within.
