The findings indicated that rural-to-urban migrant delivery workers experienced high levels of mental disorders and burnout. Regression analyses revealed that workplace violence and high job demands were significantly associated with mental disorders and high burnout, and these associations were more pronounced among rural-to-urban migrant workers.
