Cambodia is backsliding in efforts to improve working conditions in its garment industry, the International Labour Organisation said yesterday, following a series of strikes at factories producing western-brand clothing. The kingdom is failing to make progress in key areas such as worker and fire safety and the use of child labour, the ILO said in a report. … The ILO said some factories kept emergency doors locked during working hours while others failed to conduct emergency fire drills every six months. It also identified worsening heat and sanitary conditions, as well as suspected use of child labourers, in more than a dozen factories covered by its report. … Workers have staged a series of protests at low wages and tough conditions in the multibillion-dollar industry, which employs about 650,000 people and is a key source of foreign income for the impoverished country.
