Postal Service Time and Attendance System

The U.S. Postal Service (USPS) is a 24 hour, 7 day a week operation that spans the United States from the largest metropolitan areas to remote towns with less than 100 people. The Postal Service has over 800,000 employees, most of whom collect, sort, process and deliver mail. There is a time and attendance system for paying each employee; it is a critical and complex computer-system application.
