Unexpected employee departures can tarnish service delivery, harm customer loyalty, degrade quality of services, drop productivity, and hurt goodwill. The ability to predict employee churn is crucial for retaining valuable employees. This study proposes a predictive model that uses machine learning to forecast employee churn. The predictive model uses feature selection through Pearson correlation methods, information gain, and recursive feature elimination, combined with strong classification methods such as random forest, logistic regression, decision trees, gradient boosting machines, and K- nearest neighbours. The IBM dataset was used for training and testing the proposed predictive model. The accuracy of the different algorithms improved after applying particular feature selection methods. The results yielded showed that the random forest technique outperformed other models in terms of accuracy in the prediction of employee churn.Keyphrases: employee churn, feature selection methods, machine learning models, prediction In: Hossana Twinomurinzi, Nkosikhona Theoren Msweli, Tendani Mawela and Surendra Thakur (editors).
