The Council of Trade Unions says contractors are often afraid to rock the boat

It welcomes potential employment law changes to clarify the difference between contractors and employees

Auckland Scaffolder Jahden Nelson was recently electrocuted on a building site, but as an independent contractor, didn't have the same rights as an employee.

CTU Secretary Melissa Ansell-Bridges says contractors can be very vulnerable.

She says their ability to earn a living is in the hands of the person engaging them.
