TL;DR
In January 1914, Ford Motor Co. raised minimum daily pay to $5 and cut its workday from nine hours to eight, amid severe worker turnover linked to the demands of its increasingly efficient assembly line. The episode’s account says turnover fell from 370% in 1913 to 54% in 1914; the familiar claim that Ford acted mainly so workers could buy his cars is not supported by the evidence presented.
A November 6 account of Ford Motor Co.’s early assembly line revisits the company’s January 5, 1914, five-dollar day: Ford cut the workday from nine hours to eight and raised minimum daily pay from $2.34 to $5 as it struggled to keep workers. The change followed a sharp increase in production efficiency, but the account says the immediate problem was extreme employee turnover, not a shortage of customers or a plan to make workers buyers of Ford cars.
The account draws on figures from Henry Ford’s 1922 book, My Life and Work, as well as a 1987 study by economists Daniel Raff and Lawrence Summers. Ford’s company figures put the labour required to assemble a Model T chassis at 12 hours and 28 minutes when the vehicle remained stationary. By early 1914, after work was reorganized around a moving line, the figure was 1 hour and 33 minutes—about 88% less labour time per chassis.
Ford’s line experiments began with a small component, the flywheel magneto, in 1913. The account says the company divided its assembly into separate tasks and moved the part past workers. Ford reported that the time to assemble one magneto fell from about 20 minutes to 13 minutes and 10 seconds, then to five minutes after further adjustments. The production method was later extended to the chassis and engine.
The speed gains coincided with workers leaving at a high rate. Raff and Summers’ study, as described in the episode, reports 50,448 hires in 1913 to maintain an average workforce of 13,623, a turnover rate of 370%. The account says turnover fell to 54% in 1914, after Ford introduced the higher pay and shorter day. The new $5 rate was paid as profit sharing and carried conditions; the source does not give their full terms.
The Human Cost of Faster Production
Ford’s production gains illustrate a tension that remains relevant to manufacturing: a process can make each unit faster to build while making the work difficult to sustain. In the account’s telling, dividing assembly into repetitive tasks helped cut labour time, but the company’s need to replace tens of thousands of workers made the production system costly and unstable.
The five-dollar day therefore matters as both a wage policy and a response to a workforce problem. The reported fall in turnover suggests that higher pay and shorter hours coincided with improved retention, though the figures alone do not establish how much each change contributed. The episode also pushes back against a familiar story that Ford raised wages chiefly so employees could afford his cars. It says the company’s pressing issue was workers leaving, not insufficient demand for vehicles.
The longer view is more complicated than a simple story of machines eliminating jobs. The source says U.S. factory employment rose by about a third between 1910 and 1920, even as assembly methods changed. That historical comparison does not predict what automation will do today, but it shows why productivity, job numbers and the quality of work should be considered separately.

From Stationary Chassis to Moving Line
Before Ford’s moving line, workers assembled a car around a stationary chassis, bringing parts to the vehicle. Ford’s Highland Park plant in Detroit tested a different arrangement in 1913. In the first chassis experiment described in Ford’s book, a rope and windlass pulled the chassis along a 250-foot route while six assemblers walked beside it. Ford said this reduced labour time to 5 hours and 50 minutes. Further changes to the line and division of tasks brought the figure down to 1 hour and 33 minutes in early 1914.
The episode attributes an early influence to overhead rails used by Chicago meatpackers, where carcasses moved past workers. Ford wrote that the assembly-line idea came “in a general way” from that system. That explanation is Ford’s own account, published in My Life and Work with journalist Samuel Crowther in 1922; the episode explicitly treats it as the company’s version of events rather than an independent production record.
The workforce figures also come through different sources. Raff and Summers’ 1987 research used historical labour data, while the Henry Ford museum is cited as giving a turnover estimate of about 380%, slightly above the 370% reported in the study discussed by the episode. Ford later wrote that the company had to hire about 53,000 people annually in 1914 to maintain a force of 14,000. These estimates point to severe churn, but they are not identical measurements.
“The reduction of the necessity for thought on the part of the worker and the reduction of his movements to a minimum.”
— Henry Ford, in My Life and Work (1922), as quoted in the episode
What the Turnover Figures Establish
The episode presents turnover figures from more than one source, including 370% from the study it cites and about 380% from the Henry Ford museum. Ford’s later estimate of roughly 53,000 annual hires refers to 1914, while the 50,448 figure is given for 1913. The measures and years should not be treated as interchangeable.
The reported drop to 54% turnover in 1914 follows the pay and hours change, but the material does not isolate the effect of the higher wage from the shorter workday or other changes at the company. It also does not provide the full eligibility rules for the profit-sharing arrangement. The account says the popular explanation that Ford acted so workers could buy his cars is a legend, but it does not supply a separate detailed analysis of company sales or management deliberations.
Some of the production figures come from Ford’s own 1922 account, written years after the line’s introduction. They are attributed as company figures in the episode, not presented as independently verified measurements. The source also does not establish how workers experienced the conditions across different jobs or how the pay arrangement affected every employee.
The Assembly Line’s Longer Legacy
The episode places Ford’s 1914 decision in a longer history of factory work: U.S. factory employment rose by about a third from 1910 to 1920, according to the source, while assembly-line production spread. It closes by noting that assembly lines remain in use, with more tasks now performed by robots. That observation is broad context, not a claim that automation has produced the same effects as Ford’s system.
The next point for readers is how the gains and costs of production change as factories adopt new technology: whether output rises, how work is reorganized, and what happens to wages, hours and employment. The historical account does not answer those current questions. It does show that Ford’s famous pay decision followed a specific challenge—keeping workers in a fast-changing workplace—and that the available evidence does not settle every detail of why the policy succeeded.
Key Questions
What did Ford change in January 1914?
Ford cut the workday from nine hours to eight and raised minimum daily pay from $2.34 to $5, paid under a profit-sharing arrangement with conditions.
Why did Ford introduce the five-dollar day?
The episode says Ford was responding to severe turnover as workers left the company in large numbers. It argues that retention—not a plan to help employees buy Ford cars—was the immediate business problem.
How much faster did the assembly line make chassis work?
According to figures attributed to Ford’s account, labour time per Model T chassis fell from 12 hours and 28 minutes when stationary to 1 hour and 33 minutes on the moving line by early 1914.
How high was turnover at Ford in 1913?
The episode cites a 370% turnover rate and 50,448 hires to maintain an average workforce of 13,623. It also notes that the Henry Ford museum gives a slightly higher estimate of about 380%.
Did the five-dollar day cause turnover to fall?
The episode reports that turnover fell to 54% in 1914 after the wage and hours changes. The figures show a decline after the policy, but they do not establish how much of the change was caused by pay, shorter hours or other factors.
