A humorous yet insightful anecdote recounts how a simple data entry error in the Job Control Language (JCL) led to the United States Postal Service (USPS) overpaying $500 million to 150,000 employees. This incident occurred due to a JCL operator entering the wrong year, compounded by the unexpected federal holiday following Ronald Reagan's death, which left no one in the finance department to catch the mistake. The USPS payroll, one of the largest and most complex systems globally, was disrupted, causing a massive overdraft and requiring a collaborative effort over the weekend to correct the error. The situation necessitated intervention from the Secretary of the Treasury and took several months to resolve, highlighting the critical nature of detail-oriented work in large-scale systems and the occasional unpredictability of life events intersecting with technology. Remarkably, no one was fired over the incident, and the tale serves as a reminder of the non-technical challenges faced by those in technical roles.
