Honk Kong pop star Jacky Cheung has been banned from hiring maids from the Philippines after sacking 21 in just three years. The ban has been imposed by the Philippines consulate, which has placed Cheung on its list of substandard employers for a year. It also means Cheung - nicknamed 'The Terminator' by disgruntled former staff - won't be allowed to renew the contracts of the four Filipina maids he currently employs.
