While urban planning and design scholars are yet to capture the full impact of the COVID-19 crisis some studies indicate that the COVID-19 pandemic is altering our use of, and patterns of behaviour in, public space. Physical and social distancing, staying at home notices or other limitations in place are disproportionately impacting some socio-economic groups, along lines of ethnicity, class and gender. Despite the growing body of work on the impact of COVID-19 on the use of public space, few studies focused on vulnerable social groups, as the ones with precarious education, work and housing situations. Through several cases in Hong Kong, in this presentation we explore the use of urban streets and elevated pedestrian systems by migrant domestic workers (MDWs), before and after the pandemic outbreak. Before the pandemic outbreak, the Sunday gathering of these (mainly) women, live-in workers providing essential care services, has been described as contributing to the creation of a cosmopolitan landscape with a variety of uses in streets, urban parks and other public spaces. The analysis reveals changes in behavioural patterns of uses and identifies public space surveillance measures that might jeopardize the richness and variety of activities in urban streets. The presentation discusses the ongoing conflictual renegotiation of rights and space along with the dual nature of invisibility of vulnerable groups. The growing invisibility of migrant workers catalyses the emergence of questions of rights, spatial and recognitional justice and acceptance of diversity in the global neoliberal city.
