Last month, Cadbury announced a proposal to cut 45 supervisor and leading-hand roles, and create 19 new positions, as part of a management shake-up.
"After careful consideration of all the proposals put forward by our employees, we can now confirm that our original proposal has been accepted," Cadbury spokesman Daniel Ellis, of Melbourne, said.
The move will result in the loss of 26 jobs, which are part of the 145 redundancies announced by the plant in August.
Seventy redundancies have been confirmed so far.
Those affected by the announcements were asked to apply for one of the 19 new front-line leader positions, with those unable to secure a position to leave the company by the end of the year, he said.
"We are currently developing a transitional plan to support our people through these changes over the coming months."
Cadbury is also proposing cutting 17 trade roles, with existing employees encouraged to apply for one of six positions.
A decision on trade roles would be made within the next two weeks, he said.
