Just to leave an example - what do you expect will think someone sweating in stress and efforts all day long, working close to coworker better paid with apparently less work/effort involved? That that coworker is better at what he/she does? You'd be lucky! That one will more likely think that the system is unfair. As I mentioned in another comment (and should have mentioned in the article), this is a natural consequence of transparency: it demands fairness. There is nowhere for unfair compensation schemes to hide with full transparency. So in your example, the underpaid worker would naturally demand to be paid fairly. And the response to that better be something like "yes, this is how we'll do it" - otherwise, you're right, they will leave (a good call, if they're working in a company that treats them unfairly). This is definitely a plus for the employees. From your username you sound Romanian (I was born there, my parents left just after I was born and I grew up in Switzerland). I know from my parents that Romania under communism was a pretty horrible place. But I also know from talking to them that it was a place that was full of fear and mistrust. We're using transparency to increase trust, and it works. Sure, from one angle, if you squint the right way, it looks like some sort of "communist" nonsense to open up all this information, but I can assure you that at least at the scale we're at, the effect is to increase trust and empower people, not to reduce them to fearful subjects of the state.
