Fired for Contacting Jeff

We had an awesome manager last year, but after he got a new boss due to Amazon's constant and unnecessary reorganizations, he was really treated badly and unfairly. He complained to HR about it, but they refused to do anything other than tell him to just accept it or else leave. 

After Jeff sent his email this past August telling everyone to email him their management problems, he did exactly that and was very honest about his situation. They fired him less than a week later, which really demoralized everyone in our group since it's apparent that no one in Amazon senior managers cares about the truth.
