The COVID-19 pandemic is a mobilizing circumstance for rethinking the economic activities of companies, as well as reorganizing the way employees work. To comply with the regulations imposed worldwide, most economic activities were transferred to the online environment. The purpose of the paper is to carry out an investigation of the Romanian telework system implemented during the pandemic based on the perception of employees and employers. Our research was conducted based on an online opinion poll in which 438 respondents participated. The questionnaire included the socio-demographic characteristics of the respondents, methods and techniques for implementing telework among Romanian companies, and a correlation of the advantages and opportunities with the limits experienced both among companies and employees in carrying out this process. The results showed that 7.80% of companies wanted to maintain the conditions implemented for telework, 12.30% wanted to expand flexible practices to promote telework, and 27.60% would not make any changes in terms of telework methods. At the same time, 81.10% of employees preferred office work rather than teleworking. Successful implementation of the telework system involves efficient management that coordinates and motivates the performance of remote employees.

In a world where use of technology is not an option but a necessity, where new forms of work appear constantly, where change is everywhere and people must keep their distance from each other due to the pandemic, organizations must adapt and use new processes governed by using new technologies. In a sustainable environment, e-recruitment and non-financial compensations become the new tools to maintain performance and lower costs during a pandemic. Using bibliometric analysis, regression function, and correlation matrix, the authors obtained results for Romania and the top three countries, which indicated that e-recruitment is influenced by the use of the internet and availability of computers and productivity; the relations and the correlation between the analyzed variables are measured using simulation and mathematical modeling. The results indicate that there are benefits for individuals, for organizations, and also for environmental protection.
