TL;DR
Ford’s moving assembly line reduced the labor time to assemble a Model T chassis from 12 hours 28 minutes to 1 hour 33 minutes by early 1914, according to company figures. But the faster, repetitive work coincided with extreme turnover, and Ford responded on Jan. 5, 1914, by shortening the workday and raising the minimum daily wage to $5 under a conditional profit-sharing plan.
Ford’s moving assembly line cut the labor time needed to build a Model T chassis by about 88%, but the production gains came alongside severe worker turnover that helped prompt the company’s five-dollar day in January 1914. Ford shortened the workday from nine hours to eight and raised minimum daily pay from $2.34 to $5 through a conditional profit-sharing plan, according to a historical account published by ThorstenMeyerAI.com on Nov. 6, 2026.
Ford’s own figures, later published in Henry Ford’s 1922 book My Life and Work, put chassis assembly at 12 hours 28 minutes per vehicle when workers assembled a stationary car. By early 1914, after the company introduced a moving line and divided tasks among workers, the figure was 1 hour 33 minutes. Those numbers reflect the company’s account of its production changes.
The process developed through experiments at Ford’s Highland Park plant in Detroit. In April 1913, workers began assembling the Model T’s flywheel magneto on a moving line. Ford wrote that the idea drew in part from overhead rails used by Chicago meatpackers. The magneto task was split into smaller operations; Ford’s account says assembly time fell from about 20 minutes to 13 minutes and 10 seconds, and then to five minutes after further changes.
The pressure on workers was stark. A 1987 study by economists Daniel Raff and Lawrence Summers reported that Ford hired 50,448 people in 1913 to maintain an average workforce of 13,623, a turnover rate of about 370%. A company survey from March that year found many workers were classified as having quit after missing five consecutive workdays. The five-dollar plan included strict conditions, and its pay was not simply an unconditional wage increase.
Productivity Came With a Labor Cost
The assembly line became a defining production method because it greatly reduced the time and labor needed to build a car. Ford’s figures show the scale of the change: chassis assembly fell from 12 hours 28 minutes to 1 hour 33 minutes. The process also broke work into narrowly defined, repetitive tasks, changing what factory jobs demanded of workers.
The five-dollar day matters because it links manufacturing efficiency to labor retention. The source account says turnover fell to 54% in 1914 after the pay and hours changes, though that figure does not by itself establish how much of the drop the policy caused. The arrangement also tied higher pay to conditions, making the program more than a straightforward across-the-board wage rise.
The account challenges the familiar explanation that Ford raised wages chiefly so workers could afford to buy Ford cars. It says the company’s immediate problem was keeping enough people in its jobs: in 1913 it needed tens of thousands of hires to sustain a workforce of about 13,600. That distinction changes the story from a simple consumer-sales strategy to a response to the costs of high turnover.

From Stationary Cars to Moving Lines
Before the moving line, workers assembled a car around a chassis that remained in one place, bringing parts to the vehicle. Ford’s experiments began with a small component before extending the method to the full chassis. In an early trial, a rope and windlass pulled a chassis along a 250-foot path while six assemblers moved with it; Ford’s account says the work then took 5 hours 50 minutes.
Further changes raised the line to waist height, divided the work more finely and adjusted its speed. The source account says Ford’s workers found that 44 inches per minute worked better than trials at 60 inches or 18 inches per minute. The company applied similar methods to engines: its figures put motor assembly at 9 hours 54 minutes in October 1913 and 5 hours 56 minutes six months later.
The five-dollar plan followed on Jan. 5, 1914. Ford’s account later described the company as having to hire about 53,000 people a year to maintain a workforce of 14,000. These figures and the production-time comparisons largely draw on company records and Ford’s retrospective account, while the turnover estimate is associated with Raff and Summers’ later study. The different sources and periods should not be treated as identical measurements.

Limits of the Historical Record
The production figures are principally Ford’s own reported numbers, published in a book nearly a decade after the experiments. They document the company’s account, but the source material does not provide an independent measurement of every reported time or a full breakdown of how the figures were calculated.
The reported fall in turnover from 370% in 1913 to 54% in 1914 is a major change, but the figures alone do not establish how much came from the five-dollar plan rather than other conditions. The plan also had eligibility requirements, and the supplied account does not fully detail how many workers qualified, how pay was calculated for each participant or how consistently the policy was applied.
The wider effects on workers’ health, household finances and later wage policies are not quantified in the material. Nor does it provide a detailed comparison with other automakers. Those limits leave the scale of the five-dollar day’s broader influence open to further historical evidence.
The Historical Account’s Next Questions
The source is a published historical account rather than a report of a newly announced policy or an ongoing investigation. It does not identify a forthcoming official decision or next event. The next step for readers seeking a fuller assessment is to compare Ford’s retrospective production figures with company records and independent research, including the Raff and Summers study cited for turnover.
Further research could clarify who qualified for the profit-sharing arrangement, how the company enforced its conditions, and how workers experienced the pace and repetition of line work. The account also points toward a longer industrial history in which assembly lines persisted while more factory tasks came to be performed by machines, but it supplies no specific current figures on automation.
Key Questions
What changed at Ford on Jan. 5, 1914?
Ford cut the workday from nine hours to eight and raised minimum daily pay from $2.34 to $5 through a conditional profit-sharing plan.
How much faster did the moving line make chassis assembly?
Ford’s figures put the time at 12 hours 28 minutes for a stationary chassis and 1 hour 33 minutes on the moving line by early 1914. That is a reduction of about 88% in labor time, according to the company figures cited in the account.
Why did Ford introduce the five-dollar day?
The account presents it primarily as a response to high worker turnover. Ford hired 50,448 people in 1913 to maintain an average workforce of 13,623, according to figures cited from a 1987 study.
Was the five-dollar wage available to every worker without conditions?
No. The source describes the increase as conditional profit sharing with strict requirements. It does not give a complete account of eligibility or how many workers received the full amount.
Did Ford raise wages so workers could buy its cars?
The source account disputes that common explanation as the main reason. It says Ford’s immediate challenge was keeping workers, not finding customers, while noting that the company’s turnover figures and the precise effects of the policy should be read with their source limitations in mind.
