Today I'm over at ProSky, and I'm talking to your boss again!
The subject is one of our major requirements for happiness - as humans, and as employees:
Progression.
You need growth; I need growth; we all need it. We thrive with it, and we get restless/bored/unhappy/unfulfilled without it.
So I'm giving your boss some ideas for giving progression to you! The post is HERE. Let me know in the comments what your ideas are!
