>Unions would not fix this. Badly run, they would swap charm for seniority. The reason why unions often settle on age/experience as a way to measure seniority is because it's objective so it makes a decent compromise. If you leave it up to management they will usually end up rewarding/promoting those who pledge fealty to them over those who are more skilled, and union sympathizers will be singled out and punished no matter how skilled or productive.
