Executive summary
AI is often described as the fourth industrial revolution, and it can feel like the fastest. This piece looks at how the earlier ones changed the way people worked, why the link between better technology and shorter hours seems to have stalled since the 1980s, and what firms can take from the businesses that got it right last time.
We are in the middle of one of the great industrial revolutions, and it may prove to be the biggest yet. The pace is overwhelming. New tools arrive every few months, each one asks something new of us, and most of us are trying to keep up while doing a full job.
Firms have done remarkably well with it. People in law and accounting practices have taught themselves a technology that was barely in workplaces a few years ago, and they have done it around client deadlines.
The speed is new, but workers and business owners have been through industrial revolutions before, and each time they faced questions we would recognise. What will this do to our jobs? How do we keep up? Who benefits? We can look back at what they did, see what worked, and use it to manage the flood of AI arriving in our working lives.
1Four revolutions
When most of us think of the Industrial Revolution, we picture Henry Ford and the motor car. Ford belongs to the second one. A common framework describes four, and each has followed a similar pattern. A new technology arrived, output per worker rose, workplaces were rebuilt around it, and over time conditions for workers improved, including the hours they worked.
Steam
The first revolutionThe first revolution began in Britain in the late 1700s, when water and steam power let factories mass-produce goods for the first time. Life inside those factories was hard, with very long days, and it took organised workers decades to bring the hours down.
Australia played its part. In April 1856, Melbourne's stonemasons, led by James Stephens, downed tools on the University of Melbourne building site and marched through the city. After months of negotiation they had an eight-hour day, paid at the rate they had been getting for ten, according to the National Museum of Australia. It applied to a fairly small group of tradesmen at first, and many workers, women and children among them, kept working longer hours for years.
Electricity
The second revolutionThe second revolution, from the late 1800s, brought electric power, the electric motor and the assembly line. This is Ford's revolution, and it changed working hours as well. In May 1926, Ford moved its factory workers to a five-day, 40-hour week. "It is high time to rid ourselves of the notion that leisure for workmen is either 'lost time' or a class privilege," he said.
Australia moved in the same direction. According to the Fair Work Commission's history, the Arbitration Court set a 44-hour week for the engineering industry in 1927, and after the Second World War the Standard Hours Inquiry set a 40-hour week, which took effect in January 1948, with some industries exempt at first.
In the middle of all this, in 1930, the economist John Maynard Keynes wrote an essay called Economic Possibilities for our Grandchildren. He predicted the standard of life a hundred years on would be "between four and eight times as high as it is to-day", and suggested his grandchildren might work "three-hour shifts or a fifteen-hour week". He also wrote about a fear that sounds very familiar now, which he called "technological unemployment". His hundred years are up in 2030.

Computers
The third revolutionThe third revolution began with computers and software from the 1960s, although many businesses did not reorganise around them until the 1980s and 90s, when they became something everyone in the office could use. Even in the year to June 1994, only 49% of Australian businesses used a computer at all.
Computers also arrived as Australia's workforce moved from making things to providing services. Services made up 63% of Australian jobs in the 1960s and 84% by the 2000s. The Reserve Bank links the shift mainly to rising incomes and changes in trade, but it meant computers arrived just as office work was becoming most of the work. From 1983, the standard week came down to 38 hours, award by award.

AI
The fourth revolutionThe idea of a fourth revolution was popularised by Klaus Schwab of the World Economic Forum, who set it out in January 2016, when automation and machine learning already seemed well under way. Ten years on, the pace has picked up beyond what most people expected. Generative AI came into offices only a few years ago and is now being built into many of the tools firms use every day. And the fear Keynes wrote about is back, with many people worried that AI could take their jobs.
Put those dates side by side and the pattern from the first three revolutions is easy to see, up to 1983.

2Since 1983
For more than a century, better technology went hand in hand with a shorter working week. Since the 38-hour week began spreading through awards in 1983, the standard has not moved in 43 years.
For a while, the hours people actually worked went the other way. The Australian Bureau of Statistics found the average full-time worker did 38.8 hours a week in 1985 and 40.9 hours by 1995, the decade computers moved onto most desks. Usual hours across all workers have eased since, from about 37 a week in 2001 to around 35, and part of that fall comes from more people working part-time.
Productivity has slowed as well. In February 2026 the Reserve Bank told a Senate committee that labour productivity growth has slowed in recent decades compared with the 1990s and early 2000s. On AI, it said the "measured benefit of this is yet to be observed in Australia."
Economists have been puzzled by this before. In 1987, Robert Solow wrote in the New York Times Book Review:
You can see the computer age everywhere but in the productivity statistics.
Robert Solow, 1987
The economic historian Paul David went looking for the reason and found a parallel in electricity. Many of the first factories to buy electric motors put a big one where the steam engine had been, and ran the building the old way, with the same layout, the same drive shafts and the same flow of work. The large gains came decades later, once factories were designed around electricity from the ground up.
What we are seeing in firms today looks a lot like that first factory. AI is often going into ways of working that were built around a person at every step. A person drafts, a person checks, a person forwards, a person files. Each step gets a little faster while the shape of the work stays the same, however hard people work at it, and the time saved tends to drift back into more of the same work.

3Rebuilding the factory
Train people properly
Each earlier revolution created demand for new skills. Typists learned word processing and bookkeepers learned spreadsheets. Learning works best when it is built into the working week with time set aside for it, and people find it hard to pick up between clients. Our post on AI training in onboarding is a good place to start.
Set the safety rules early
Electricity came with wiring rules. Computers came with passwords, backups and IT support. AI needs the same kind of groundwork: what can go into which tool, which outputs need checking, and who does the checking.
Put the structure in first
When offices brought in computers and the internet in the 90s, they needed cabling, servers, IT support and a person responsible for all of it before the machines paid off. For AI, that means an owner in the firm and a shared way of working that the whole team follows.
Let go of the old tasks
Some tasks exist only because of how the work used to be done: figures retyped from one system into another, or a file note summarised three times for three different people. Before asking AI to do a task faster, ask whether the task still needs to exist.
Start from scratch, on paper
If you set up your firm today, with the tools available now, what would a client matter look like from the first call to the final invoice? Some of the answer will take years to put in place. It will still show where AI fits the work as it is, and where the work needs to change around AI.
The first electric factory
- A new motor where the steam engine stood
- The same layout and the same flow of work
- Small gains at each step
- Time saved drifts into more of the same
The rebuilt factory
- The work redesigned around the new technology
- A shared method across the whole team
- Gains that add up across the firm
- The firm chooses where the saved time goes
The stonemasons answered it by marching through Melbourne, and later generations answered it through the arbitration system. This time, a firm can answer it for its own people before the saved time disappears into more work. We look at the options in What to do with the time AI gives back.
And don't worry too much. Computers came into business in the 1960s, and thirty years later more than half of Australian businesses still did not use one. Electricity took decades to pay off. We are only a few years into this revolution, which means there is time to get it right.
A firm can start with the foundations now and take small steps. Most of the early work is practical: an agreed set of tools, a few shared rules, time set aside to learn, and a decision about what the saved time is for. Done well, this revolution can give people better working conditions, with less of the burnout and overwhelm so many are feeling right now.
4Where we come in
Every revolution so far has meant rebuilding the workplace around the new technology, and that starts with knowing how the work is done now. Our investigation maps your firm's work step by step and measures how long each part takes, so you can see which parts are ready for AI and which need rethinking first. The findings belong to your firm whether or not we go any further together.
If you would like to work out what rebuilding looks like for your firm, reach out to our team. The first conversation works out whether your firm is the right fit for the AI Uplift Program, and whether we are the right people to help.

0 of 6 doneFrequently asked questions
What are the four industrial revolutions?
A common framework describes four: steam and mechanisation from the late 1700s, electricity and mass production from the late 1800s, computers and software from the 1960s, and the current wave of automation and AI, which Klaus Schwab of the World Economic Forum popularised as the fourth industrial revolution.
When did Australia get the eight-hour day?
Melbourne's stonemasons won an eight-hour day in 1856, at the same daily pay they had received for ten hours. It covered a small group of tradesmen at first and spread over the following decades.
When did the 38-hour week start in Australia?
The Arbitration Commission's National Wage Case in September 1983 opened the way for a 38-hour standard week, which spread through awards over the following years. It is now set in the Fair Work Act 2009 as part of the National Employment Standards.
Has AI made Australia more productive yet?
In February 2026, the Reserve Bank said the measured benefit of AI is yet to be observed in Australia. Earlier technologies such as electricity and computers also took years to show up in productivity figures.
Why do new technologies take so long to pay off?
Businesses often add a new technology to the way they already work. The larger gains have tended to come once the work itself is redesigned around the technology, which took decades for electricity and computers.
