This article aims to highlight the importance of human resources within an organization. In this sense, we have analysed the evolution of the concepts mainly related to personnel and human resource, as well as their management. Today, organizations, and society as a whole, are facing the need to change methods, working techniques and find new ways of working, adapting to the crisis caused by the COVID-19 pandemic. We argue that the human resource of an organization is the most affected resource and requires special treatment from managers both during the pandemic and in the post-pandemic period. The benefit is on the part of the organization by maintaining efficient staff and, respectively, by ensuring performance and productivity.
