Impact of enforcing a statutory minimum wage on work and quality of life of vulnerable groups in Hong Kong

The statutory minimum wage (SMW) law was enforced in Hong Kong on 1 May 2011. To examine its impact, this longitudinal study measured the quality of life, job and pay satisfaction, monthly income, hourly rate and working hours of vulnerable groups (n = 253) before and after the legislation. The findings confirmed that the enforcement of the SMW induced a positive impact as intended. The introduction of the SMW induced a positive wage and employment effect on the vulnerable groups in Hong Kong without harming their employment rate. Job and pay satisfaction, as well as most domains of the quality of life (i.e., physical and psychological health, and environment), increased significantly. In general, the positive impact of the SMW was more prominent for employees who previously worked less than 18 hours a week and who had hourly rates less than 28 HKD. The implications of the findings are discussed in the social context of Hong Kong.
