Attrition refers to the gradual reduction in the number of employees or participants through resignation, retirement, or other natural means, rather than through layoffs or terminations. To address the questions and rephrase them into a cohesive paragraph: Attrition is a term that signifies the slow decrease in the workforce or group members due to voluntary departures such as resignations, retirements, or other organic reasons, as opposed to forced reductions like layoffs or terminations. This concept is often used in human resources and organizational contexts to describe the natural ebb and flow of personnel without the need for direct intervention. By understanding attrition, organizations can better manage their staffing levels and plan for future workforce needs.
