Three Foxconn workers have committed suicide at a factory in China in the past three weeks, state media and a labour rights group said on Saturday.
All three jumped to their deaths at a plant in the central city of Zhengzhou run by the Taiwanese electronics giant.
A 30-year-old married man killed himself on Tuesday following the similar deaths of a 23-year-old woman on April 27 and a 24-year-old man three days earlier, the Xinhua news agency reported.
“The reasons for these building jumpings are unclear,” the New York-based China Labor Watch rights group said in a statement.
Foxconn, which assembles products for Apple, Sony and Nokia, has come under the spotlight after suicides and labour unrest at its Chinese plants since 2010.
In 2010, at least 13 Foxconn employees in China died in apparent suicides, which activists blamed on tough working conditions, prompting calls for better treatment of staff.
At the time, Nokia commented on the many suicides.
“We are concerned and take this very seriously. Given the concerning reports regarding Foxconn, we are in continuous contact with Foxconn to ensure any issues are identified and addressed as soon as possible,” was the statement from Nokia in 2010.
Foxconn is the world’s largest maker of computer components and employs up to 1.1 million workers in China.
