TL;DR
Ford’s account says its moving assembly line cut the labor required to assemble a Model T chassis from 12 hours 28 minutes to 1 hour 33 minutes by early 1914. At the same time, the company faced high turnover and absenteeism, and on Jan. 5, 1914, it raised minimum daily pay to $5 while shortening the workday to eight hours.
Ford’s moving assembly line sharply reduced the labor time required to build a Model T chassis, but the efficiency gains arrived alongside a workforce crisis: in 1913, the automaker hired more than 50,000 people to maintain an average workforce of about 13,600. On Jan. 5, 1914, Ford responded by cutting the workday from nine hours to eight and raising minimum daily pay to $5, a change the company presented as profit sharing.
According to figures Henry Ford published in My Life and Work in 1922, assembling a chassis took 12 hours 28 minutes of labor when the car remained stationary. By early 1914, after Ford moved the chassis along a line and divided the work into smaller tasks, the time had fallen to 1 hour 33 minutes—about 88% less labor time. Those numbers come from Ford’s own account, not an independent production audit.
The process developed through trials at the company’s Highland Park plant. Ford wrote that the first assembly-line experiment, around April 1913, involved the flywheel magneto, a small generator used in ignition. Dividing that task into 29 operations reduced the time reported for assembling one magneto from about 20 minutes to 13 minutes 10 seconds. Later changes to the line and its speed cut the time further, according to Ford.
The labor savings did not mean the line was easy to staff. Figures cited by economists Daniel Raff and Lawrence Summers in a 1987 study put Ford’s 1913 turnover at 370%: the company made 50,448 hires to sustain an average workforce of 13,623. The source also reports that one worker in ten was absent on an average day. On Jan. 5, 1914, Ford announced the higher minimum wage and shorter day. The $5 rate came with conditions attached to the profit-sharing plan.
Productivity Met a Labor Shortage
The episode shows how factory efficiency and worker retention became linked at Ford. A line that shortened the labor needed for each chassis still depended on enough people showing up to perform repetitive, tightly divided tasks. High turnover meant the company continually had to recruit and replace workers, disrupting the operation that was supposed to make production more efficient.
The $5 day matters as a prominent early example of an employer changing pay and hours in response to staffing problems. The source frames the move as a response to turnover, rather than as a simple effort to make workers able to buy Ford cars. That distinction changes the explanation of the policy: it connects higher wages to the costs of replacing workers and keeping production running. The material does not establish that this was the only reason behind Ford’s decision.
The broader labor picture also cautions against assuming that new production methods immediately reduced the number of factory jobs. The source says U.S. factory employment rose by about a third between 1910 and 1920, even as manufacturing methods changed. That national figure is a separate measure from Ford’s own workforce and does not by itself show how the assembly line affected employment at individual plants.

From Stationary Chassis to Moving Line
Before Ford’s line experiments, workers assembled a car around a stationary chassis, bringing parts to the vehicle. At Highland Park, the company’s reported best average was 12 hours 28 minutes of labor per chassis. The moving-line approach changed both the location of the work and its organization: the product traveled, and each worker handled a narrower set of operations.
Ford wrote that the broad idea drew on overhead rails used in Chicago meatpacking plants, where carcasses moved past workers. The first car-chassis trial was rough: a rope and windlass pulled the chassis down a 250-foot track as six assemblers moved alongside it. Ford said this version cut labor time to 5 hours 50 minutes. Later, the line was raised and tasks were divided further, bringing the reported figure to 1 hour 33 minutes in early 1914.
The pay change followed a period in which workers frequently left or stopped attending. A March 1913 company survey, as described in the source, recorded about 7,300 departures in one month. It classified 71% as “five-day men,” workers who had missed five consecutive days and were counted as having quit. That classification reflects the company’s accounting practice; it does not explain each worker’s reason for leaving.
““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
Limits of Ford’s Production Figures
The production-time figures largely come from Ford’s own 1922 account, and should be read as company-reported figures rather than independently verified measurements. The source also notes that the $5 wage had strict eligibility conditions but does not detail them fully, so the headline daily rate should not be taken to mean every worker automatically received the same amount.
The evidence summarized here links the wage change to turnover, but it does not establish every motive behind Ford’s decision or describe how workers experienced the new line and pay rules. The source’s claim that the familiar explanation—workers were paid more so they could buy Ford cars—is a legend is an interpretation; the material presented points instead to staffing costs, without ruling out other considerations.
How the Pay Plan Was Measured
The reported result was a sharp decline in turnover: the source puts Ford’s rate at 54% in 1914, down from 370% in 1913. That change supports the view that the pay-and-hours policy helped stabilize staffing, though the figures alone do not isolate the effects of wages from other changes at the company.
To judge the policy more fully, readers would need details on who qualified for profit sharing, how much workers actually received, and how turnover was calculated across both years. The source also points to a longer shift in factory work: assembly lines remain in use, while more tasks are performed by robots. It offers no current figures on the share of work automated, so that comparison remains broad rather than quantified.
Key Questions
What changed on Ford’s assembly line?
Ford moved the chassis past workers and divided assembly into smaller tasks. In Ford’s account, labor time per chassis fell from 12 hours 28 minutes to 1 hour 33 minutes by early 1914.
Why did Ford introduce the five-dollar day?
The source identifies severe turnover and absenteeism as the immediate problem. It says Ford raised minimum daily pay to $5 and shortened the workday to eight hours on Jan. 5, 1914, under a conditional profit-sharing plan.
Did every Ford worker receive five dollars a day?
Not necessarily. The source says the payment came with strict conditions but does not set out the full eligibility rules or explain how many workers qualified.
How reliable are the reported production-time figures?
The figures are attributed mainly to Henry Ford’s My Life and Work, published in 1922. They are useful company-reported measures, but the material does not present them as independent audits.
