Synchronizing the Workplace

"Scientific management" experts promised that work synchronized to a uniform time standard would increase productivity and efficiency. Many factories installed electrical systems in which a master clock controlled secondary dials throughout a building, bells and whistles, and even time stamps for marking paperwork. Schools, department stores, and hospitals also installed electric time systems.

Punching the Clock
Time was money—in wages for the worker and in products and profits for the employer. Time clocks, first invented in the 1880s, were a tool for controlling time. By about 1910, as the influence of "scientific management" spread, nearly every blue-collar workplace had a time clock.

Timing Work
Managers sought to save time by measuring and controlling the amount of time a worker spent on any task. Frederick Winslow Taylor began a series of pioneering stopwatch studies in the 1880s. He timed each component of a given task, then streamlined them to speed completion in the name of efficiency. His work inspired generations of industrial engineers, who used the stopwatch in their research until the 1960s. Stopwatch studies often antagonized those being timed. Workers were sometimes prepared for studies with morale-boosting pamphlets.

Speedy efficiency became the manager's ideal in workplaces of all kinds—from factory floors to business and professional offices to churches. Wartime urgency added to the sense that time was a kind of pressure. Posters urged workers to make every minute count.
