1. Working hours: The working hours of black workers in the UK often exceed normal working hours. Workdays for low-skilled jobs in the UK typically last between nine and 12 hours, as well as more than 60 hours a week. In the country's most heavily regulated industries, the workweek can be up to 48 hours, but many black workers often labor overtime and are not even paid overtime.

2. Salary: Chinese migrant workers in the UK earn far less than normal. Their wages are very low, usually only 3 to 4 pounds per hour, or even less than 2 pounds in some industries. And the minimum wage in the UK is ￡8.72 per hour, which means that black workers usually only get half or even less of what workers get paid.
