Following the 2013 electoral setback and post-election protests, the ruling Cambodian People’s Party has pursued policy concessions to mobilise support from workers in the garment industry. This article examines the role of government-aligned unions in vote mobilisation. It is argued that despite their under-performance in the 2013 election, government-aligned unions retain the trust of the Cambodian People’s Party leadership and continue to play a vital role in facilitating co-optation by communicating public policies and political messages to workers, influencing the minimum wage determination process, and delivering free healthcare services. This article contributes to the growing literature on the Cambodian People’s Party’s post-2013 adaptation and the broader literature which often focuses on labour unions in single-party regimes.
