A worker, dressed in bright yellow and wearing a protective cap and face mask, carries a bolt of vivid red fabic at a textile factory. Most textile workers in Bangladesh earn little more than the minimum wage which is set at 3,000 Taka per month (approx. GBP 25). Around 4 million people, mostly women, work in the garment industry. The industry is worth around GBP 12.5 billion a year.
