Luis and Amy are programmers employed by X Corp. They work in cubicles next to each other. Both have M.Sc. degrees in computer science (Luis also has a Ph.D. in philosophy). They are about the same age, and have been with the company since its birth. Luis codes games, while Amy codes a variety of projects. Although their work is different, both jobs require the same skill level. Luis makes $100,000 a year, while Amy makes $80,000. If Amy sues X Corp. because of the pay differential, what must she show? What might the company argue in defense? Who should win?
