Work-from-home (WFH) during the COVID‑19 pandemic has become a common strategic choice for organisations to continue their day-to-day office work. Now, organisations need to be critical about the future implication of WFH. This paper aims to examine employees' sentiments regarding WFH during the pandemic by analysing Twitter posts. Using ScraperWiki, it collects and archives random Twitter data spanning 755882104 tweets regarding employee attitudes and opinions about WFH across 245 pandemic days. Results explore that WHF has the positive and supportive potential as a remote work strategy to increase workplace flexibility and effectiveness for greater employee engagement and organisational sustainability. This paper will help scholars and practitioners understand how to better manage workplace flexibility by applying WFH in challenging times.
