BANGKOK (Thomson Reuters Foundation) - Tun Tun Win and his co-workers from Myanmar thought life was fine at the Thammakaset chicken farm in central Thailand, where they reared hundreds of thousands of birds for export to the European Union.
The migrants clocked 20 hours a day for 40 days straight, shoveling litter and culling the sick among the birds as they grew from chicks to poultry for slaughter.
Then 10-hour days for three weeks cleaning the warehouse-sized coops at the Thammakaset chicken farm in Lopburi province.
And finally they got three days off.
All that work for what they figured was a fair wage: nearly $7 a day, with free rent and electricity.
"We thought our employer was a nice guy because he gave us rooms, and we didn't have to pay rent," Tun Tun Win said. "We stayed for free, and we got our money."
More than 3 million migrants work in Thailand, the vast majority from neighboring Myanmar, according to the International Organization for Migration.
Many are exploited on farms and in factories across the country, facing an uphill battle for compensation and justice against multi-tiered corporate supply chains, rights groups say.
That's if they even know they're being exploited in the first place.
It was a smartphone and a Facebook post that opened Tun Tun Win's eyes to the severity of his work conditions - and led to a landmark lawsuit pitting migrant workers against a corporation at the top of the food chain.
The case highlights widespread ignorance among both workers and employers about labor rights, and workplace norms seen as violations in the closely scrutinized global supply chain.
It all began last year after Tun Tun Win bought a new phone, and a "chicken doctor", one of the farm's veterinarians, introduced him to social media.
Lying in bed next to his wife one night, he saw a post about tuna plant workers from Myanmar who had been overworked and underpaid. They had received more than $1 million in an unprecedented settlement in March.
The Facebook post by the local non-profit Migrant Worker Rights Network (MWRN) inspired Tun Tun Win and 13 co-workers to take action.
In a lawsuit filed at a labor court earlier this month following unsuccessful negotiations with the company and local authorities, they are demanding $1.3 million in compensation and civil damages.
The suit alleges forced overtime, unlawful salary deductions, passport confiscation and limited freedom of movement.
Crucially, the action is against both Thammakaset and the buyer of the farm's poultry - agricultural giant Betagro, which exports food worldwide.
Andy Hall, a prominent British human rights activist in Thailand who has consulted on several cases involving migrants, said the litigation was an important test case.
"We're trying to hold Betagro responsible for the system of contract farming," he said. "If we can, it will have huge implications for contract farming and the responsibility of corporate supply chains across Thailand."
Part of the workers' evidence includes pictures snapped on Tun Tun Win's phone and shared on Facebook, including time-stamped cards - one showing a worker clocking in on May 24 at 6:54, out at 17:00, in again at 19:02, then out at 5:37.
That's a total of 20 hours and 41 minutes.
In an interview, Thammakaset owner Chanchai Pheamphon said he had not fully understood the requirements under Thai law and agreed he had underpaid staff as well as illegally deducting rent and utilities from their daily wages.
But he denied charges of forced labor or limiting employees' freedom of movement, and said he planned to file a counter defamation suit against the workers and MWRN.
"I'm now facing bankruptcy," he told Thomson Reuters Foundation, adding that a decision by Betagro to halt business with Thammakaset amid the controversy had forced him to shut his 1.6 million-chicken, three-farm operation and lay off nearly 100 employees.
"This NGO (MWRN) wants more money for these 14 workers, but what about the 100 others?" he said. "The world has already found me guilty, and they have stopped buying my goods. They've already sentenced me to death."
Betagro, one of Thailand's largest meat producers and exporters, also denied the workers' allegations.
"There were no violations of human rights or anything resembling forced labor, as defined by the law on prevention and suppression of human trafficking," it said in a statement.
Other than the statement, Betagro did not respond to email and phone requests for an interview.
ABUSE AND IGNORANCE
Supply chains for goods such as food, clothing and electronics usually begin in countries with the cheapest labor.
Thailand has been at the center of scores of reports of slavery and human trafficking, with migrants from Myanmar suffering the worst exploitation.
In the face of mounting scrutiny of supply chains, Thailand has strengthened laws to crack down on labor exploitation, while other countries have passed legislation to address abuses abroad.
Britain's 2015 Modern Slavery Bill requires businesses to disclose actions taken to ensure their supply chains are free of slave labor.
In February, U.S. President Barack Obama signed the Trade Facilitation and Trade Enforcement Act, banning imports of goods made with forced labor into the United States.
Yet at the lowest rungs of supply chains, rights groups say many businesses such as Thammakaset fall short of global standards - even if owners like Chanchai defend working practices.
He said staff voluntarily worked nights to rack up bonuses.
"We paid them to work during the day, but we didn't forbid them from working at night," he said, adding that they chose to sleep in hammocks in the room next to the chicken warehouse.
"They play on the Wi-Fi, then go and look at their chickens. They don't have to work, but they just might think that if they raise the chickens well, they will get more money."
Flipping through a bound file of documents, Chanchai showed photos of the workers drinking at a restaurant and swimming, and of the low fence around his farm that he said proved they were free to come and go as they pleased.
He said he deducted $2 from their $8.60 legal minimum daily wage for rent, drinking water and electricity, and made cuts such as a 14 cent fine for not picking up dead chickens.
With the fines collected, he would buy a gold necklace for a raffle at the workers' year-end party, he said.
Hall, the rights activist, said the workers were told if they did not work overnight, they would face salary deductions - a charge Chanchai denies.
Commenting on the 14 cent deduction for not picking up dead chickens, Hall said: "That is illegal. Any deduction from the salary is illegal. He has acknowledged that he has unlawfully deducted money from them."
Hall added that it was common for employers and officials to rationalize violations, revealing a mindset in which only the most extreme conditions or acts - such as putting workers in chains - constituted crimes.
"These people just don't understand that what they're doing is abuse," he said. "They don't think of it as forced labor or modern-day slavery. They don't understand how people could level such allegations against them."
