Idea Services' support workers will start getting paid the minimum wage for sleepover shifts within the next eight weeks.
The IHC business provides services for people with intellectual disabilities including supported living, where workers may be required to spend the night.
Until now, care workers were being paid a $34 allowance, plus their hourly rate for each time they had to get up and tend to the needs of occupants. They will now be paid per hour when required to spend the night at a supported living home.
Local Idea Services support worker Aneta McMeeking said it was a huge relief that the four-year fight for better pay was at an end.
"What we've achieved is a fight for recognition," she said.
