Retention refers to the ability of a company to keep its employees, customers, or other stakeholders over time. In the context of employee retention, this means the ability of a company to prevent its employees from leaving and to maintain a stable and engaged workforce. High employee retention can be a sign of a positive and supportive work environment, as well as good management and leadership. In the context of customer retention, this means the ability of a company to keep its customers coming back and to maintain a high level of customer satisfaction and loyalty.
