I am definitely worth more now; I agree. Unfortunately: 1) Management in all but one job I've had invested nothing in training and helping new employees grow.

I am definitely worth more now; I agree. Unfortunately: 1) Management in all but one job I've had invested nothing in training and helping new employees grow. My technical growth has come through personal projects and taking on extra work. 2) Promotion never offered anything like the salary increases a new job offered. The incentive to stay is not there.
