A world first opt-out union membership system is being proposed for New Zealand.
The idea from four academics would see workers signed up to a union at the same time as they sign their employment contract.
Waikato University Management Professor Mark Harcourt told Heather du Plessis-Allan that right now, the system is opt-in, which makes it hard for unions to gather members who are afraid of offending their new employer.
He says people can still choose to be part of a union, or not part of a union, under an opt-out system.
Harcourt says research shows widening income inequality is linked to the decline in union presence.
