Trade unions in Southern Africa are in trouble. Membership is falling. Collective bargaining coverage is shrinking. In sector after sector, workers are entering the labour market through arrangements — casual contracts, gig platforms, labour brokers — that the traditional union model was never built to handle.
And yet, in the same region, unions are negotiating wage agreements that cover millions of workers, running training programmes that reach into rural communities, and shaping national labour policy in ways that no other civil society actor can match.
The picture is contradictory because the reality is contradictory. Trade unions in SADC are neither dying nor thriving. They are in transition — and what happens next will shape the working lives of tens of millions of people across the region.
This article examines where SADC trade unions stand today, what is driving their decline, and what genuine revitalisation looks like in practice.
How We Got Here
Trade unions in Southern Africa reached their peak influence in the 1980s and 1990s. In South Africa, the Congress of South African Trade Unions (COSATU) played a central role in the struggle against apartheid and in shaping the post-1994 democratic settlement. In Zimbabwe, Zambia, and Malawi, union movements were active forces in the push for multiparty democracy.
The democratic transitions of that era came with expectations. Workers had fought for change. They expected the new political order to deliver decent wages, enforceable labour rights, and a seat at the policy table.
In some respects, it did. Labour legislation across the region improved significantly through the 1990s and 2000s. Collective bargaining frameworks were formalised. Tripartite structures — bringing together government, employers, and unions — were established in most SADC countries.
But structural changes in the economy began to erode the foundations on which union power rested. Privatisation reduced employment in the public sector, historically a union stronghold. Trade liberalisation exposed manufacturing industries to competition that drove down wages and casualised employment. And the growth of the informal economy created a vast pool of workers who fell entirely outside formal labour relations structures.
The result, across most of SADC, has been a slow but steady decline in union density — the share of the workforce that belongs to a union.
“Trade unions in SADC are neither dying nor thriving. They are in transition — and what happens next will shape the working lives of tens of millions of people across the region.”
What the Research Shows
Zonge Research International has been closely involved in research on trade union dynamics in Southern Africa, including work commissioned by the International Labour Organisation and other regional partners.
A study on trade unions in transition across Southern Africa — examining the future of work in the context of structural change — found several consistent patterns.
Union density has declined in most SADC countries over the past two decades, but the decline is uneven. Unions in the public sector, mining, and manufacturing have held their ground better than those in agriculture, services, and construction. Women workers and young workers are significantly underrepresented in union membership across the region.
Collective bargaining coverage — which matters more than membership alone, because it determines how many workers benefit from negotiated agreements — has held up better than membership figures suggest in some countries. But in others, bargaining councils have weakened or collapsed entirely, leaving workers without effective wage floors.
A separate baseline study on trade unions in Malawi found that most unions lacked the financial resources, organising capacity, and technical skills to effectively represent their members. Many were heavily dependent on check-off systems — employer-deducted membership fees — which created structural vulnerabilities whenever an employer chose not to cooperate.
The same study found that workers, including non-members, still broadly believed that unions were necessary and valuable. The crisis was not one of legitimacy. It was one of capacity and reach.
The Four Drivers of Decline
Understanding what has weakened trade unions in SADC requires looking at four overlapping forces.
Informalisation of work. The most fundamental challenge is structural. Across Southern Africa, formal employment — the traditional terrain of union organising — has contracted relative to informal work. Casual labourers, piece-rate workers, domestic workers, and street vendors now make up the majority of the working population in most SADC countries. Traditional union models, built around the workplace as the site of organising, struggle to reach workers who have no fixed employer, no stable workplace, and no contract.
Fragmentation of the labour movement. Union proliferation — the emergence of multiple, competing unions in the same sector — has weakened collective bargaining power in several SADC countries. Employers have learned to play unions off against each other. Rivalries between union federations have diverted energy from organising into internal politics.
Hostile regulatory environments. In some countries, legislative changes have made it harder to strike, easier to dismiss workers, and more difficult to organise in sectors where employers are resistant. The gap between rights on paper and rights in practice remains wide.
The gig economy and platform work. Newer forms of work — food delivery platforms, ride-hailing apps, online freelancing — are expanding rapidly in Southern Africa’s cities. Workers in these sectors are typically classified as independent contractors, placing them outside the coverage of most labour legislation and beyond the reach of traditional union structures. Research by Zonge Research International-affiliated researchers on gig workers in South Africa found that platform algorithms exercise near-total control over workers who have no formal employer relationship and no access to collective bargaining.
“The crisis of trade unions in SADC is not one of legitimacy. Workers still believe unions are necessary. It is a crisis of capacity and reach.”
What Revitalisation Actually Looks Like
The concept of union revitalisation is well established in labour studies. It refers to the process by which declining unions rebuild their membership, influence, and capacity to deliver for workers. Several models have been tried across the globe. Some have worked. Many have not.
In the Southern African context, research points to several approaches that are showing genuine results.
Organising beyond the workplace. The most promising shift in union strategy across the region has been the move towards community-based organising — reaching workers where they live rather than only where they work. Unions that have built relationships with community structures, women’s groups, and informal traders have found new pathways to workers who were previously unreachable.
Sector-wide bargaining. In sectors where individual workplace bargaining is impractical — domestic work, agriculture, construction — sector-wide agreements that set minimum standards for all workers, regardless of employer, have proven more effective than enterprise-level negotiation. Extending bargaining council agreements to non-parties, where legislation allows, has a similar effect.
Coalitions with civil society. Unions that have formed durable alliances with NGOs, faith-based organisations, and community groups have been able to extend their reach and amplify their advocacy. The most effective coalitions in the region are those built around shared interests — housing, health, climate — rather than narrow membership concerns.
Young worker and women’s programmes. Union membership skews male and middle-aged across most of SADC. Organisations that have invested seriously in dedicated structures for young workers and women workers — not as token committees, but as genuine organising priorities with resources attached — have seen membership and energy recover.
Digital organising tools. WhatsApp, social media, and mobile-based communication have opened new possibilities for reaching workers in dispersed employment. Several unions in the region have used these tools effectively to coordinate action, share information, and build solidarity across workplaces that could never be reached through traditional shop steward structures.
The Role of Regional Coordination
One of the distinctive features of labour organising in Southern Africa is the regional dimension. Workers cross borders in large numbers. Labour standards in one country affect conditions in others. And employers — particularly in mining, agriculture, and construction — operate across multiple SADC jurisdictions.
SATUCC — the Southern Africa Trade Union Coordination Council — plays a critical role in coordinating trade union positions at the regional level, engaging with SADC policy processes, and supporting national affiliates on issues that cannot be addressed at the country level alone.
Research conducted for SATUCC on regional integration and decent work found that the most effective regional union work happened when national affiliates had the capacity to implement regional commitments at home — which many did not. Regional solidarity is meaningful only when it is backed by strong national organisations.
The ILO’s manual on trade union revitalisation in Southern Africa — developed with input from Zonge Research International researchers — drew on experience from across the region to identify what works. Its central conclusion was straightforward: revitalisation requires sustained investment in organising, not just in servicing existing members.
Bargaining in the Age of Climate and Technology
Two forces are reshaping the bargaining agenda across SADC in ways that unions are only beginning to grapple with.
The first is climate change and the just transition. As coal plants close and green energy projects expand, unions face questions about job losses, retraining, and the terms on which new energy industries will be organised. Unions that are not at the table when just transition plans are drawn up will find their members on the wrong side of the energy shift.
The second is technology and platform work. Automation is beginning to affect employment in manufacturing, retail, and transport across the region. Platform work is growing in urban centres. Unions that cannot organise gig workers or influence the terms of algorithmic management will represent a shrinking share of the workforce.
These are not future problems. They are present ones. The unions that revitalise successfully in SADC will be those that treat both as central organising challenges — not as issues to be addressed once the membership crisis is resolved.
What Governments and Employers Must Do
Union revitalisation is not only the responsibility of unions. Governments and employers have obligations too.
Governments must enforce existing labour legislation rather than allowing it to exist only on paper. They must extend legal protections to informal workers and platform workers. And they must ensure that tripartite structures are genuine forums for dialogue — not rubber-stamp processes that produce agreements without accountability.
Employers must recognise that strong unions are good for productivity, not just for workers. Workplaces with effective collective bargaining have lower turnover, fewer disputes, and higher trust. The short-term gains from union-busting come at a long-term cost to labour relations and workplace stability.
International donors and development finance institutions that fund programmes in the region must stop treating trade unions as a political inconvenience and start treating them as essential infrastructure for inclusive development.
The Bargaining Table Is Worth Saving
Trade unions are not perfect institutions. They have, at various points across the region, been captured by political interests, failed to represent women workers fairly, and prioritised the concerns of formal employees over those of the informally employed.
But they remain the only institutions that exist specifically to represent workers’ collective interests in the labour market. No other actor — not NGOs, not government social protection programmes, not corporate social responsibility initiatives — can substitute for the function that collective bargaining performs.
Revitalising the trade union movement in SADC is not a nostalgic project. It is a practical necessity for anyone who believes that economic growth should translate into decent wages, safe workplaces, and dignified working lives for the people who generate it.
At Zonge Research International, we are committed to producing the research that helps our partners make that case — and build the evidence base for union revitalisation that is grounded in the realities of Southern Africa today.
