Each organization is, in essence, an open economic entity both at its entry and exit, otherwise it would not be able to exist in the market. The same applies to the movement of employees into and out of the organization. The share of these arrivals and departures must be of a certain degree that is optimal or at least tolerable for the given economic entity. The outflow of key employees in a short period of time can lead to dysfunction with an impact on the entire organization. In relation to employee movements, we distinguish the concept of turnover from the analysis of employee departures. Fluctuation in its content includes not only departures of employees from the organization but also joins the organization.
