I think there has to be reform in management.
You have to start by establishing a career plan for each individual. You also have to show them how to aspire to management. To manage, you have to have values and genuinely be able to communicate with the people who report to you so they feel they're part of a team. Then they'll want to introduce reforms.
However, if no one trusts the leaders because many of them, particularly those at lower line levels, have abused their power, it's hard to do anything.
On the other hand, it's also hard to identify the guilty parties in management at an enormous organization such as this one and to get rid of them quickly. This reform will be a major effort, and I think it will take several years.
