Call for de facto compulsory unionism

NewstalkZB reports:

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.

Yeah, Nah.

But if implemented I propose all taxpayers be automatically made members of the Taxpayers Union, with an ability to opt out.
