t you are forgetting the graduated pay scale. also unions have job descriptions which pay differently. For instance the operating engineers have different pay scales such as air compressor operator, crane operator. oiler, mechanic foreman etc. the same structure could be in the food service industry. chief cook, bottle washer, cashier. same with the business you are in. Medicine. running the circumcising machine for instance has potential for advancement, forty skins a week and a chance to get a head. on the other hand I have no sympathy for doctors who let huge medical conglomerates screw them out of the AMA. 15 bucks is doable for the food industry.
