Employment Relations Act 2000, s 103(3)
Triangular employment is where you’re employed by one employer but you spend your day working directly for someone else – for example you’re employed by a labour hire company but work day-to-day for another company on a building site. This can be a short-term or long-term arrangement.
Until recently workers employed by labour hire companies who were sent to work day-to-day under the control of another company (called a “controlling third party”) could only bring a personal grievance against their employer (the labour hire company) and not against the third party who was supervising their work at the time.
