Seven years ago, the summer of 2019 transformed Hong Kong. What began as a million-strong march against a draconian extradition bill rapidly evolved into something far deeper: a fundamental awakening of collective power. As political protests filled the streets, an unprecedented grassroots trade union movement quietly took root. Across disparate sectors from finance and transport to healthcare and the civil service, workers discovered that solidarity could achieve what spontaneous street actions could not, building an organised, formidable force capable of bringing the territory to a standstill at pivotal moments.
Although a subsequent national security crackdown shattered Hong Kong’s civil society, forcing independent unions to disband and incarcerating their leaders, that brief, historic flourish left an indelible mark. It demonstrated that behind the frontline clashes was a workforce learning to stand together.
The turning point came in August 2019. An initial call to strike two months earlier had faltered, exposing the fragility of ad-hoc mobilization. But by 5 August, operating without centralized leadership, a citywide strike mobilized 350,000 workers—the largest political walkout Hong Kong had witnessed in nearly half a century.
That single day awakened a wave of labour organising. Between late 2019 and early 2020, the appetite for unionisation exploded on an astonishing scale. While the Registry of Trade Unions had received a modest 16 registration applications in the whole of 2018 and 142 in 2019, the first three months of 2020 alone saw a staggering 1,578 submissions. By the end of that year, nearly 500 new unions had entered the official register, representing a seismic shift in how Hong Kongers viewed workplace organization and political agency.
Spearheading this new wave was the Hospital Authority Employees Alliance (HAEA). Formed in December 2019, it quickly grew to 22,000 members. When COVID-19 struck the territory in February 2020, the HAEA staged a historic five-day strike, the first major collective action by local healthcare staff demanding border closures and adequate protective gear. For its chair, Winnie Yu, defending her colleagues and defending Hong Kong were inseparable duties.
That commitment carried a heavy personal cost. After participating in an unofficial pro-democracy primary ahead of the 2020 Legislative Council elections, Yu was arrested in 2021 and later convicted of conspiracy to commit subversion. Handed an 81-month prison sentence, she remains behind bars, with an appeal decision due shortly. Under intense political pressure, the HAEA was forced to dissolve in mid-2022.
Similar stories played out across the economy. Young professionals in education, social work, and transport established independent bodies to hold management accountable. Workers at the city’s railway operator formed MTR New Power, demanding transparency over controversial police actions in stations while simultaneously securing essential safety equipment for staff during the pandemic. These organisations proved that political consciousness and industrial advocacy could go hand in hand.
The rapid rise of the new union movement was halted abruptly on 30 June 2020 with the imposition of Beijing’s National Security Law. Independent unions vanished almost as quickly as they had emerged, their leadership silenced or dispersed.
Yet the legacy of that summer extends beyond the organizations destroyed by the state. During the 2020 healthcare walkout, Winnie Yu remarked that she hoped the strike would plant seeds for a broader understanding of labour rights and solidarity. Seven years on, those seeds may remain buried beneath political repression, but the collective memory of a united workforce endures, a lasting reminder of what Hong Kong’s workers achieved when they chose to stand together.
