HandsOn Hong Kong is a charity founded in 2007 that mobilizes volunteers to meet social needs. It helps local NGOs access volunteers by managing an online calendar for volunteer opportunities. Common barriers to volunteering include busy schedules and uncertainty about how to get involved. Effective volunteer recruitment involves identifying roles for volunteers, segmenting roles by commitment level, and using job descriptions and online sign-ups to engage volunteers. HandsOn Hong Kong aims to reduce barriers for NGOs by taking on the burden of volunteer management and coordination.
