The Aotearoa Legal Worker's Union says some lawyers are doing so much unpaid overtime they are effectively earning below the minimum wage.
It surveyed 300 of its members and found the average lawyer is now working almost an extra day each week for free.
The union says it's contributing to a bad workplace culture and burning out legal workers.
With Ingrid Hipkiss is Co-President of the union, Ollie Neas.
