Phnom Penh, Cambodia
Last week over 300 garment workers in two different Cambodian factories fainted. This past June, 200 fainted at another clothing factory.
Update: September 22, 2011
Workers at one of the sites where workers fainted, Hung Wah Garment Manufacturing, succeeded in a wildcat strike in reaction to the refusal of a supervisor to sign-off on requests for leave.
The company agreed to transfer the supervisor and the strikers returned to work.
