How did racial segregation affect Black workers in colonial Southern Africa?

Racial segregation in colonial Southern Africa fundamentally structured the economy to exploit Black labor while systematically excluding Black workers from political power and economic advancement. This system was designed to protect white interests, secure cheap labor for industries like mining, and suppress Black militancy.12

Impacts on Black Workers

• Migrant Labour System: Many Africans were forced into a migrant labor system, becoming dependent on a money economy while their rural communities suffered from congestion, soil erosion, and the loss of able-bodied workers.13
• The Colour Bar: To prevent competition, white workers demanded and secured a "colour bar," which reserved skilled positions for whites and relegated Black workers to lower-paid, semiskilled, or unskilled roles.1
• Legislative Control: Laws such as the Mines and Works Act and various industrial conciliation acts excluded Black workers from wage-bargaining machinery and trade union organization.12
• Pass Laws and Movement: The introduction of pass laws and strict residency requirements severely restricted the mobility of Black workers, forcing them to live on reserves or in segregated urban areas unless they were employed in white-owned businesses or farms.452
• Exploitation: Black workers were often subjected to harsh conditions, low wages, and minimal health protections, particularly in the mining industry.3

These policies institutionalized a racially segmented labor market that ensured Black workers remained disenfranchised and economically marginalized to serve the needs of the colonial state.32
