Employee retention is a major challenge for companies. Our work has enabled us to develop a method for identifying and extracting from the frequent patterns coming from employees' trajectories those that improve their retention. This publication shows how we have visually valorized our results. These are presented in the form of interactive dashboards, with the aim of being exploited by the company's HR managers. They offer a global visualization of attrition, an identification of employees at risk of resigning, and a simulation of the impact of an intervention.
