Due to the spread of COVID-19, new challenges and opportunities for business innovation have emerged, including the way work is organized and designed. In particular, pandemic created the conditions for the most extensive mass teleworking experiment in history. While there is a wide literature on the effects of teleworking as a business innovation, mainly from an environmental perspective, there are few studies investigating the public perceptions regarding teleworking and, in particular, studies that draw from social media analyses. Based on these considerations, a big data analysis has been carried out in order to frame the public perceptions about teleworking on Twitter. The six-months sentiment analysis of about 11,000 tweets shows that the ecological value of telework is not perceived by people; surprisingly, in a pandemic context of growing ecological concern, there is no significant evidence of environmental awareness in relation to teleworking. However, the positive and negative concepts which emerge in relation to teleworking and similar terms can be assimilated to the benefits and pitfalls highlighted in the literature, which are related to economic or social sustainability. This has important implications for practice in organizations employing teleworking, which are highlighted in the conclusion, together with the limitations and future research avenues.
