FINANCIAL TIMES - A spare shilling in your pocket in May 1906 would have got you into London's hit attraction that season: an exhibition hall filled with haggard "home workers" bent over their trades.
Placards next to each person explained to onlookers their hours, their pay and a few biographical details. No. 15, for instance, made bonnets to support herself and "two weakly children" after she "lost her husband in a very tragical manner".
The exhibition was organised to highlight the plight of "sweated workers": Factories would subdivide work and parcel it out via middlemen to people (often women) working at home for miserly piece rates.
Working from home is no longer usually associated with poverty and desperation.
In fact, as this year's pandemic has underlined, to "WFH" in 2020 is a privilege confined mostly to the well paid. European data suggests three-quarters of jobs in the highest-paying quintile can be done remotely, compared with just 3 per cent of those in the lowest quintile.
But there is a seemingly futuristic way to earn money from home without a professional job. It's called crowd-work and people are flocking to it because of Covid-19.
Strip away the 21st-century gloss, and it wouldn't look out of place in that exhibition hall.
Crowd-work platforms enable companies to split virtual jobs into small tasks, then offer them to home workers to complete anywhere in the world.
Like Uber drivers and other gig economy participants, crowd-workers are classed as independent contractors and paid by the task. But they are virtually invisible and no one knows how many there are.
Janey, from a small former mining town in the United States, became a crowd-worker after the father of their three children died of an opioid overdose. "If I work 12 to 16 hours a day, I'll make maybe US$5 (S$6.80) an hour," she said in an interview in a research paper by University of California Hastings law school professor Veena Dubal.
Janey works on crowd-work site Amazon Mechanical Turk (AMT), where there is no minimum wage and many "requesters" pay only a cent or two per task.
"There are so many of us now and fewer quality jobs. Sometimes I wake up in the middle of the night just to see if I can grab some good requests."
The "good requests" are available only to workers who have already completed a vast number of tasks and who maintain a high acceptance rate. If your work is rejected (fairly or unfairly), you don't get paid.
Many tasks involve cleaning or labelling data for companies developing artificial intelligence. Academics also use crowd platforms to recruit participants cheaply and quickly for surveys.
In 2017, researchers recorded 2,676 workers performing 3.8 million tasks on AMT, and found the median hourly wage was US$2 an hour. Only 4 per cent earned more than US$7.25 an hour.
The competition is global: Workers in the US earn US$3.01 per hour on average, while those in India earn US$1.41. Prolific, a United Kingdom-based crowd-work platform for surveys and market research, imposes an hourly pay floor by calculating the average time it takes workers to complete each task.
But while the UK's legal minimum wage for over-25s is £8.72 (S$15.30) an hour, Prolific's is £5 an hour.
Why do people do it? Just as with the home workers at the turn of the 20th century, some dabble for pocket money to fill their spare hours, while others depend on it because they live in an employment black spot, have disabilities, want to stay at home with their children or cannot afford childcare.
This year, the pandemic has created the perfect conditions for huge growth in crowd-work: There is mass unemployment, a shortage of childcare and a higher risk of dying of Covid-19 if you do a more traditional low-paid job such as social care.
"You deserve to be safe too," urged a recent advert for Arise, a virtual call centre platform where people have to pay for their own equipment and training, and can then work from home.
As historian Helen McCarthy details in her book Double Lives, some Edwardian reformists wanted to drive home work into factories and "set (women) free for domestic duties". In the US, some types of home work were banned altogether.
Patronising paternalism would be the wrong response today. People are choosing to work on these platforms because they want, or need, to work from home.
If only the rich are to be allowed that privilege, it will open another fault line in a divided society.
But that doesn't mean the opportunistically low rates of pay, opacity and powerlessness built into these platforms should be allowed to continue unchecked.
Improvements will require regulation, unionisation and, in countries like the US, a better social safety net so people are less desperate.
German crowd-workers rely less on the platforms than US ones, a difference researchers attribute to Germany's superior social protections. In July, one in five Americans with children at home couldn't afford to feed them enough, according to census data.
For many, working from home now feels like the future. But if we aren't careful, for some, it will mean a return to the past - one that our forebears fought hard to leave behind.
