The research utilizes a qualitative descriptive approach, with a case study chosen as the research method to address the research questions. Data collection techniques include interviews, observations, and document analysis. The data obtained are further validated through triangulation of data. The findings indicate that self-learning contributes to improving employee readiness for work, while leadership mentoring helps address horizontal mismatches among managers.
