Suppose you had a system at work that allowed you to evaluate the performance and effectiveness of your coworkers. You could log on at any time and leave an opinion that would only be viewable by your boss and his bosses.
And imagine that you could be as unprofessional as you liked. If you think your coworker is an obstructionist idiot with fake credentials, you can express your opinion in those words. Management in this hypothetical world wouldn’t want anyone diluting strong opinions with business jargon.
The idea would be to weed out employees who do a good job of concealing their treachery, toxicity, and incompetence in front of management. And in some cases it would force managers to do what they had been avoiding, namely getting rid of the bad seeds.
Obviously the system would be abused to some extent. You would have employees trying to settle personal scores, and paranoids falsely accusing coworkers of stealing and lying. But that probably happens just as much without this system. The point of the system is to gather input from more sources than just the crazies who tend to speak up.
You could call it a ratting system instead of a rating system. Would it make the workplace a better or a worse place to be?
