How are you Shaping your Job?

“I’m in a dead end job.” “My job is operational, we do routine work. There’s no opportunity for learning or innovation.” “I have ideas but my boss doesn’t act on them.” “I want more responsibility but my boss isn’t giving it to me.”
Are you at the mercy of your job description? Can you re-define your job into what you want it to be? How do you know if you can shape your job or if it’s time to get a new job?
