Rock stars are good at what they do and most of the time earn that label. Don't form a gang and hurt productivity of your team/company. If someone is working hard to earn a rockstar label don't penalize them. You will probably need rock stars and plumbers getting along well. If someone is a bad employee rockstar or otherwise that needs to be dealt properly.
Regardless, the article is spot on in describing what to do to produce healthy environments, whereas most uses of the term rock star that I've found come from unhealthy ones.
