The Court of Appeal has agreed to hear arguments over whether workers at the Bluff aluminium smelter have been given enough days in lieu after a roster change.
Shift workers at the Tiwai Point smelter moved from eight-hour to 12-hour days in 1991 but continued to be credited eight-hour days in lieu.
The Employment Relations Authority said they should have been credited with 12-hour days and upheld the decision on appeal in May this year.
In June, owner New Zealand Aluminium Smelters (NSA) asked the Court of Appeal for a hearing. The court today released its judgement granting a hearing into whether the Employment Court erred in its interpretation of the Holidays Act.
