suppose you have been a shift manager at a restaurant for several years. over your time there, the owner has put you in charge of payroll and scheduling for all shifts, not just your own. you feel like you are not being paid for the extra responsibility and sit down with the owner to discuss a raise. your boss has said on several occasions that you are saving him $15,000 a year because he does not have to hire a contractor to do payroll and scheduling. you are currently making $25,000 a year, and you would accept a minimum raise of $5,000 a year.
