The informal economy in Zambia encompasses a significant portion of the labour force but is often overlooked in formal labour legislation. A qualitative approach grounded in existing literature on labour law and social justice theories, with an emphasis on empirical case studies from Zambia's informal economy. The theoretical framework identifies key themes such as vulnerability to exploitation and discrimination, which require targeted legislative interventions to ensure fair treatment of all workers. Policy makers are encouraged to develop tailored labour laws that address the specific challenges faced by informal sector workers in Zambia.
