A few blocks from the site of the disaster, one of the worst ever industrial accidents, Ripon Das earns 15,000 taka ($141) per month for working a seven-day week as a machine operator. As his family’s sole breadwinner, it is nowhere near enough.

“I choose to work overtime without holidays to supplement my scant wages,” said Ripon, 27, whose sister had to resign from her job at the same factory after falling ill because she was not entitled to paid sick leave.

While labor advocates say safety has improved significantly in the world’s second-largest clothing exporter since the collapse of the Rana Plaza factory building, they say progress on better pay and conditions — from sick pay to insurance benefits — has been far slower.

As annual inflation running close to 10 percent hikes living costs, union leaders representing the sector’s 4 million workers are demanding a raise in the sector’s minimum wage to 23,000 taka from the 8,000 taka fixed in 2018 and revised every five years.

“Earlier I could buy food items for two to three days with just 100 taka, but now I can’t afford the same items with even 500,” said Jolly Akter, 27, a union leader who works as a garment quality inspector.

A spokesperson for the government-led minimum wage board — which also includes factory owners and labor representatives — did not immediately respond to a request for comment.

Global fashion brands that source goods from Bangladesh should support the workers’ pay demands, said Christie Miedema from the Clean Clothes Campaign, a global alliance of trade unions and non-government organizations.

She also urged them to back another key demand — insurance cover for workers who are injured while doing their jobs — following the government’s launch of a pilot last year.

Miedema said brands should factor in the costs related to the injury insurance scheme in the sales price of their garments, and that the pilot should turn into a permanent system enshrined in the country’s labor laws.

The site where the eight-story Rana Plaza building once stood is now an open field, overgrown with lush greenery. A small cement sculpture depicting a clenched fist holding a hammer and sickle commemorates the victims of the disaster.

Rajib Das, 27, whose brother was killed in the collapse of the building on April 24, 2013, often visits the site.

“Sanjit – just two years older than me and my closest sibling – supported me as I was the only one from the family to pursue higher education,” he said.

The family received a one-off compensation payment under a deal between the government and brands that sourced from the collapsed factories, but Rajib said there was no long-term program to help survivors and victims’ families to recover.

More than $30 million was paid out as compensation to the victims, but the payments concluded in 2015.

The lack of adequate social protection schemes in Bangladesh meant many injured Rana Plaza survivors were left to fend for themselves, said Amirul Haque Amin, president of the National Garment Workers Federation, a trade union.

“Many of the survivors are struggling to find a decent livelihood,” he said.

About 2,500 people were injured in the garment industry’s deadliest recorded incident, many of them seriously.

The disaster put pressure on global brands to improve factory conditions, and substantial safety improvements have been made, labor advocates and industry leaders say.

“The Rana Plaza collapse was the never again moment for Bangladesh’s garment sector,” said Amin from the garment workers federation.

About 200 fashion brands, including top names like H&M and Zara, formed an agreement on fire and building safety called Accord that involved government officials, factory owners and labor leaders.

The legally binding Accord held thousands of inspections and banned unsafe factories from supplying its signatory buyers, helping make some 1,600 factories safer for 2 million workers, according to labor activists.
