The university's Information Technology (IT) support department employs numerous representatives who provide answers or solutions to problems encountered by users (students, staff, or faculty) when interfacing with the school's various information systems.

When a user encounters a problem, they are asked to document the problem and submit a "ticket" to IT support explaining the problem. The ticket is routed to a representative who analyzes the problem, proposes a solution to the user, and then closes the ticket.

Assume that service representatives receive a base salary and a year-end bonus based on their personal productivity (the number of tickets they closed during the year). The rep with the highest productivity gets the biggest bonus, the rep with the 2nd highest productivity gets the 2nd biggest bonus, and so on.

Based on this background, give three reasons (independent of each other) why this reward method might build an inequitable evaluation of a salesperson's performance.
