Platform workers are those who are self-employed and responsible for their own social protection and fulfilling their own tax obligations. Their employment relationship with the platform companies, in many countries including Vietnam, remains largely ambiguous. This research, primarily based on a survey of platform car-drivers and bike-riders in Hanoi and Ho Chi Minh City, examines the needs, prospects and strategies employed by platform drivers in voicing their opinions, organising and bargaining collectively with platform companies. The paper was written by Do Quynh Chi, Co-founder and Director of the Research Centre for Employment Relations (ERC), with the support from Friedrich-Ebert-Stiftung (FES) in Vietnam.
