Attrition
Attrition is the gradual loss of employees through resignations, retirements, or other departures. It is a normal part of running a workforce, and how much of it a company sees depends on things like job satisfaction, career opportunities, company culture, and what is happening in the broader job market.
When attrition runs high, it can shake up organizational stability, which is usually the point where a company starts looking seriously at retention and engagement.
