Do Foreign Workers Suppress Wages in SA? Analyzing Labor Data

by

This article sits within the Content Pillar: Economic Impact of Foreign Workers on SA's Job Market and explores the complex effects of foreign labor on South Africa’s job market. By examining labor data, we aim to deliver a balanced view for job seekers, employers, and policymakers.

What the data say about foreign workers and wages in SA

  • The relationship between foreign workers and native wages is nuanced and highly context-specific. In many cases, foreign workers fill shortages in hard-to-staff sectors, enabling firms to preserve operations, expand output, and invest in growth.
  • Across SA, wage movements are influenced by multiple factors beyond immigration, including demand for services, productivity improvements, minimum wage policies, and macroeconomic cycles.
  • A growing body of research emphasizes that immigration tends to have modest, localized pay effects and often contributes to overall GDP growth and employment by expanding the economy’s productive capacity.

For a broader synthesis of this topic, see:

In practice, the key question is not simply whether wages go down when foreign workers arrive, but how immigration interacts with skills, sectoral needs, and regional labor markets. The evidence points to a pattern where the most visible wage pressures are concentrated in narrow low-skilled segments with direct substitution opportunities, while many workers experience wage gains through higher productivity, better matching, and expanded economic activity.

How foreign workers influence wages: the mechanisms at work

Foreign labor can affect wages through several channels — some that could dampen pay in certain niches, and others that raise productivity and living standards across the economy. The main mechanisms include:

  • Substitution vs. complementarity

    • In some low-skilled, easily replaceable jobs, native workers can be displaced or experience wage compression if there is a large influx of foreign labor willing to work for similar wages.
    • In many cases, foreign workers complement the domestic workforce by filling skill gaps, enabling firms to take on more complex work and raise overall productivity.

  • Productivity and skills transfer

    • Foreign talent often brings specialized skills, new technologies, and different work practices that boost efficiency.
    • This productivity uplift can lead to higher output without necessarily reducing wages for SA-born workers, and can even support higher pay in skilled roles.

  • Demand-side effects

    • Immigrant workers expand the consumer base and increase demand for goods and services, which can support more hiring and wage growth across sectors.
    • Businesses facing talent shortages may invest more in training and career progression, which can translate into higher wages over time.

  • Entrepreneurship and firm formation

  • Sector-specific dynamics

    • Some sectors with persistent shortages, such as agriculture, hospitality, and certain trades, rely on foreign workers to maintain wage levels viable for business operations. Others may experience greater competition for low-skilled roles, influencing wage trajectories differently.

For a deeper look at how productivity and talent shape SA’s economy, consider:

Sectoral perspectives: where wages may feel the impact

Below is a snapshot of sectoral dynamics. The table reflects typical patterns observed in labor data analyses, emphasizing that outcomes depend on the balance of supply and demand, skill needs, and regional conditions.

Sector Potential wage impact risk Notes
Agriculture Moderate to high in some regions Seasonal and migrant influxes can affect earnings in peak periods; longer-term effects depend on local labor supply and mechanization.
Construction Moderate in certain niches Substitution risk exists where low-skilled foreign workers compete with local labor; productivity gains can offset wage pressure in the longer term.
Hospitality and tourism Low to moderate Demand-driven growth can support wages; shortages may lead to higher wages for skilled hospitality roles.
Healthcare and social care Low to moderate Skill gaps drive demand for qualified professionals; foreign nurses and specialists can complement local staff and improve service delivery.
Manufacturing and logistics Low to moderate Productivity improvements and scale effects can raise overall wages if firms expand and invest in training.
IT and professional services Low Highly skilled immigration tends to drive productivity gains and wage growth in advanced roles.
Domestic work and personal services Moderate Direct substitution pressures can occur in some markets; policy settings and enforcement influence outcomes.

Note: These patterns are context-dependent and subject to policy, regional labor market conditions, and macroeconomic trends.

Regional labor market effects: cities and differences across SA

SA’s major cities exhibit distinct labor market dynamics shaped by industry mix, housing costs, and local immigration patterns. In growth hubs like Johannesburg, Cape Town, and Durban, foreign workers often fill persistent shortages in specialized trades, health services, and tech-adjacent roles. This can:

  • Support business continuity and expansion, which in turn creates more job opportunities for residents.
  • Improve the match between workers’ skills and job requirements, raising productivity.
  • Influence wage structures in niche markets, while broader wage trends reflect macroeconomic conditions.

Policy implications: what should be done to optimize outcomes?

Policy design is crucial for maximizing the positive impacts of foreign labor while mitigating potential downsides. Key policy considerations include:

  • Immigration and visa pathways

    • Create transparent, merit-based immigration channels that align with sectoral shortages and long-term growth goals.
    • Balance short-term demand with sustainable skills development to avoid market distortions.

  • Skills recognition and training

    • Accelerate recognition of foreign qualifications where appropriate and invest in upskilling for SA-born workers to maintain wage growth and social cohesion.
    • Expand apprenticeship and workplace training programs to bridge skill gaps in high-demand sectors.

  • Sector-specific labor market coordination

    • Use targeted sectoral analyses to calibrate demand for foreign workers and prevent wage suppression in sensitive segments.
    • Encourage partnerships between industry, education providers, and policymakers to align training with labor market needs.

  • Entrepreneurship and local value creation

    • Support immigrant entrepreneurs through accessible funding, mentorship, and regulatory clarity to stimulate job creation and innovation.
    • Link entrepreneurship programs to regional development plans to maximize economic spillovers.

What this means for job seekers and employers in SA

  • Job seekers should view immigration as a factor shaping the labor market landscape, not as a simple competitor. Building in-demand skills, especially in sectors with shortages, can improve job prospects and wage growth.
  • Employers benefit from a diversified talent pool that can close critical gaps, boost productivity, and unlock growth opportunities. Strategic hiring should consider both immediate needs and long-term capability building.

Conclusion: a balanced view of wages, growth, and foreign talent

Do foreign workers suppress wages in SA? The short answer is: not universally. The evidence supports a nuanced picture where wage effects are context-specific, heavily influenced by sector, occupation, regional labor market dynamics, and the policy framework in place. When foreign labor fills genuine skill gaps, raises productivity, and expands demand, wages for many workers can rise or remain stable, while overall GDP and employment grow.

This analysis underscores the importance of thoughtful immigration and skills policies, targeted in sectors with the greatest shortages, and complemented by robust training and entrepreneurship support.
