"However, the DHBs' resistance to meaningfully improve current unsafe rostering practises has left us no choice. We have yet to see sufficient real change in the system after four years of engagement and 10 months of bargaining.
"We see no other way to secure safer rosters for our nation's doctors and the patients we care for."
The association says: "Currently resident doctors work rosters including seven nights in a row and 12 days in a row. The RDA believes this roster is unsafe for patients and unsafe for doctors."
The association wants DHBs to agree to:
• Replace seven nights in a row with a maximum of four nights in a row followed by three days off, and
• Move from 12 days in a row followed by two days off to rosters with a maximum of 10 days in a row and four days off.
