The employee turnover rate (employee fluctuation at a company) is the number of employees who leave a company by the average number of employees in a certain time period (usually a year), expressed as a percentage. Voluntary employee fluctuation comprises employees who left of their own choice, and involuntary fluctuation comprises employees who were dismissed.
In general, a certain degree of fluctuation is natural and inevitable, and is not considered to be a negative phenomenon. The fluctuation rate is influenced by a number of factors, for example, the size of the company, the sector in which the company operates and the location of the company and macroeconomic indicators, such as unemployment.
