No, we don’t need to get rid of managers, we need to stop tolerating poor management and stop using process as a substitute for management.
Leadership is about vision and behaviours, development is about support and challenge, pastoral care is about caek and inclusion.
Management is about creating space, resolving problems, stopping things becoming problems, making a positive difference to your team daily.
We need leadership, development, pastoral care and management. If any are missing then the corporate culture will fail.
Look at your own organisation. Are these four things in place? Do they exist in reality rather than just in process or rhetoric?
As a manager do you do these things? What would your team say? Honestly?
