Workers at a garment factory in Phnom Penh, Cambodia's capital, went on strike at the end of last month in protest against the dismissal of one of their union officials. The factory produces for Gap, Benetton and Adidas, whose customers have long benefited from low-cost Asian labour. But union militancy in Cambodia's textile sector can now count some successes: the minimum wage went up by $11 in July – less than the unions wanted, but enough to end the wave of strikes.
The large, even heroic, tasks of protecting rights might be declining sharply in developed nations. But they are increasingly common in the catch-up world – especially in China and elsewhere in south east Asia. In many recently (or still) communist countries, labour remains exploited and union activism is badly needed.
China is the most eye-catching example. Strikes swept through foreign-owned companies – including Honda, Hyundai, Kentucky Fried Chicken and Toyota – in the south of the country in June, in spite of heavy attention by police. Unofficial as they were, they worked. Party leaders, including Wen Jiabao, the prime minister, called for improved wages and conditions, especially for the low paid and precarious migrant workers, who have formed much of the work force in areas such as Guangdong.
