In today's economic and social conditions where uncertainty is high, the legal and social dimensions of employment policies have gained importance, and it has become even more important to examine the relationship between job security and job performance for employees and organizations. Organizations need high-performing employees to achieve their goals and gain competitive advantage in their industries.
