There are a bunch of approaches but one I like is to have everyone vote on the relative pay for each role except their own, so customer service doesn't vote on customer service pay ratio but votes on everything else. Once you have agreed upon relative pay you then take the total budget for pay and divide it among the whole staff according to those ratios. Nobody will vote for the CEO to make 300 times what someone else makes but they will vote for higher pay for jobs they don't want to have to hire again for, say shitty jobs or complex jobs. This means the hardest to hire for are retained, the ones who make work easier for others are retained, and the ones who are making life hard for others get reduced. It also means nobody will have to feel that they didn't have a fair shake, they got to vote and voice their opinion but the group has voted. Also, who really feels OK paying someone a pittance? Exactly the type of people who will be pushed out of this type of structure.
