Currently, job duties are massively transferred from in-person to remote working. Existing knowledge on remote working is mainly based on employees’ assessment. However, the manager’s perspective is crucial in organizations that turned into remote work for the first time facing sudden circumstances, i.e., SARS-CoV-2 pandemic. The main aim of our study was to analyze remote work effectiveness perceived by managers (N = 141) referring to three crucial aspects, i.e., manager, team, and external cooperation. We assumed the perceived benefits, limitations, and online working frequency as predictors of remote work effectiveness. Further, we analyzed the possible differences in remote work perception referring to different management levels (i.e., middle-level and lower-level). Our findings revealed a significant relationship between the benefits and effectiveness of managers and external cooperation, specifically among lower-level managers. Limitations, particularly technical and communication issues, predicted team and external cooperation effectiveness. The results showed remote work assessment as being socially diverse at the management level.
