Malaysia is the world's second largest producer of palm oil, the most consumed edible oil. Sime Darby is one of the largest producers.
While the industry has come under heavy criticism in recent years for destroying rain forests to make way for plantations, attention has shifted in recent years to conditions faced by its army of workers, around 80 per cent of whom are migrants.
The petition against Sime Darby — made public this week — follows two others against another of Malaysia's palm oil giants, FGV Holdings Berhad (FGV), one by a law firm and the other by a coalition of labour, environmental and social justice NGOs.
Palm oil can be found in up to half of all products currently on grocery store shelves in the US and Europe, from biscuits, crackers and cake mixes to soap, laundry detergent and many popular cosmetics brands.
