摘要:Background: Literature defines different types of flexibility and security with regard to work. Regardless of which type of flexibility or security is discussed, the consequences for individuals, organizations or employers and society are significant. Purpose: The purpose of the research was to compare and analyse the correlation between the different types of flexibility and security in work and organizational efficiency. Methodology: Data was gathered using the Computer-Assisted Web Interview (CAWI) method. A link to an online questionnaire was e-mailed to randomly selected organisations across all economic sectors in Slovenia that had a published e-mail address, either in business directories or on a company website. We asked them to forward our e-mail to their employees. The correlation between different variables was used for data analysis. Results: The results of our research show that there is a low positive level of correlation between different types of flexibility and security in the context of work and also between different types of flexibility in work and organizational efficiency. The correlation between different types of security in work and organizational efficiency is positive and medium strong. Conclusion: It is recommended that the legislators be aware of the importance of their correlation with organizational efficiency when preparing legislative amendments regarding introduction of the flexibility and security in the field of work.
