The prevalence of female domestic workers in Southeast Asian cities has necessitated comprehensive mental health support programmes. A mixed-methods approach combining pre- and post-training assessments with qualitative interviews to analyse data from 150 participants across four cities in Ethiopia. The training programme achieved a 72% increase in knowledge about mental health, with workers reporting a significant improvement (p < 0.001) in job satisfaction after the programme. The study's findings suggest that tailored interventions can markedly enhance worker well-being and retention within the domestic workforce. Future research should explore long-term impact and scalability of these training programmes across different socio-economic contexts.
