One of the unwritten rules of business is that payroll information is private and confidential. People usually do not want their co-workers to know how much they are paid. This common business practice presents a challenge for employees responsible for payroll accounting. Payroll workers handle many different types of data. The payroll department records personal information about employees, such as addresses and social security numbers, and verifies and totals time cards. In addition, each pay period, payroll accountants calculate each employee's earnings, deductions, and net pay. Why is it important for payroll employees to be trustworthy and able to maintain confidentiality?
