Pros

Freedom to be out of the office in the field is great. Fellow managers will help you when you need it but other than that its you against upper management and union employees.

Cons

Senior management has no idea what they're doing. Employees steal, customer's steal, your ideas are ignored but still you are blamed for errors while credit is stolen for your ideas.

Advice to Senior Management

Get out in the field, see what its like on the front lines and listen to your field managers, they live through it everyday.
