When Ernst & Young audited one of Nike's Vietnamese subcontractors in 1997, a copy of the audit was leaked to The New York Times, which reported that the auditor had found that a Vietnamese factory manufacturing Nike products lacked adequate safety equipment and training, and exposed workers to hazardous chemicals, noise, heat and dust. 77 per cent of workers suffered respiratory problems. Also, the factory management encouraged up to 700 hours of overtime per year in a country where the legal limit was 200 hours.59 Despite these findings and the violations of Vietnamese labour and environmental laws, Ernst & Young concluded that the factory complied with the Nike code of conduct." The leaking of the report and a critique of it by the Transnational Research and Action Centre 'generated a series of scathing articles and columns on the business pages and sports pages of newspapers across the US and around the world.' Nike now uses Pricewaterhouse Coopers as its auditor.
