Kabir Mollah said he was inspecting garments when a friend called his cellphone, screaming that the building was on a perilous tilt.
On the morning of April 24, 2013, more than 1,100 people were killed when Rana Plaza, an eight-story building that housed five garment factories on the outskirts of Dhaka, Bangladesh, collapsed in about 90 seconds.
It is considered the deadliest accident in the history of the modern garment industry, and one of the worst industrial accidents ever.

And for current garment industry workers, where has progress been made?
