Plant ideas for what you want to do, and then wait for your manager to have a brainstorm (your idea) about doing what you want to do. Educate your manager about the right way to do things. This is an ongoing job because managers are often promoted, transferred, or fired. Focus on your manager s interests, doing what he or she really wants you to do, and don t distract your manager with unnecessary implementation details. (Think of it as encapsulation of your job.) Refuse to do what your manager tells you, and insist on doing your job the right way. Find another job.
