Up to 60 workers at Bernard Matthews are facing being laid off in the wake of the recent bird flu outbreak.
Managers and clerical staff face redundancies at Bernard Matthews
Managers and clerical staff face redundancies because of a reorganisation of the business.
The company entered into a period of consultation with some of its salaried workforce which it said was likely to lead to some job losses.
The firm said it suffered difficult times since the outbreak in February which had a "major impact" on sales.
Bart Dalla Mura, UK chief executive of Bernard Matthews, said: "The decision to reorganise the business has not been taken lightly but we firmly believe that this prudent action is needed now to secure its long-term success.
"We want to thank our staff for their hard work during the avian flu outbreak and their continuing support during this challenging time for the business."
Hourly-paid workers will not be affected by the announcement.
More than 170 Bernard Matthews workers were laid off in February.
