Mary Tan is the controller for Duck Associates, a property management company in Portland, Oregon. Each year Tamn and payroll clerk Toby Stock meet with the external auditors about payroll accounting. This year, the auditors suggest that Tan consider outsourcing Duck Associates' Tan and her staff to focus on their primary responsibility: accounting for the properties under management. At present, payroll requires 1.5 employee positions-payroll clerk Toby Stock and a bookkeeper who spends half her time entering payroll data in the system. Tan considers this suggestion, and she lists the following items relating to outsourcing payroll accounting. A. The current payroll software that was purchased for $4,000 three years ago would not be needed if payroll processing were outsourced. B. Duck Associates' bookkeeper would spend half the time preparing the weekly payroll input form that is given to the payroll processing service. She is paid $450 a week. C. Duck Associates would no longer need payroll clerk Toby Stock, whose annual salary is $42,000. D. The payroll processing service would charge $2,000 a month.

Tan believes that outsourcing payroll would simplify her job, but she does not like the prospect of having to lay off Stock, who has become a close personal friend. She does not believe there is another position available for Stock at his current salary. What are other factors that might support keeping Stock, rather than outsourcing payroll processing? How should each of those factors affect Tan's decision if she wants to do what is best for Duck Associates and act ethically?
