Migrant construction workers building the ‘new Beijing’ are routinely exploited by being denied proper wages, under dangerous conditions with neither accident insurance nor access to medical and other social services, Human Rights Watch said […] an estimated 1 million migrant construction workers, hailing from other parts of China, make up nearly 90 percent of Beijing’s construction workforce […] employers routinely force migrants to work, withhold wages for up to a year, then offer a lump sum payment which is considerably below the agreed wage rate and Beijing’s minimum wage rate. Some employers refuse to pay anything at all.
