NIST does some amazing work, and some people find a niche that they thrive in. Not me. I enjoyed my work for a time, and I was good at it. My supervisors, though, would only acknowledge my contributions in hollow compliments. A promotion was nearly impossible to achieve. High performance ratings were, I was told, only for those who could "walk on water". In reality, HR reported that 17% of my peers "walk on water". HR, though, is just a tool of management, and resolving a performance rating dispute is futile.
