What are the examples of attrition?

Attrition refers to the gradual reduction of a workforce or a group through regular processes, often without immediate replacement. Examples include employees voluntarily leaving a company for new opportunities, retirement, or personal reasons. In a broader context, attrition can also refer to customer drop-off, such as subscribers canceling a service or students dropping out of a program. Additionally, in a military context, attrition can describe the reduction of forces through sustained combat losses.
