There Are Significant Business Costs to Replacing Employees (best practice)
Thirty case studies taken from the 11 most-relevant research papers on the costs of employee turnover demonstrate that it costs businesses about one-fifth of a worker’s salary to replace that worker. For businesses that experience high levels of turnover, this can add up to represent significant costs that can potentially be avoided by implementing workplace flexibility and earned sick days at little or no cost at all.
