The firm says demand for products has dropped "dramatically"
Workers at Royal Crown Derby have been told up to 30 jobs could be cut as part of a savings drive.
The bone china manufacturer, which employs 230 people in Derby, said demand for products had "fallen dramatically in the last few months".
The firm's chief executive Hugh Gibson said redundancies would be made across the business.
The company said "every effort will be made to find alternative work" for those affected.
Mr Gibson said he was still confident of Royal Crown Derby's future.
"This is a top quality company with a fine brand and product range, and a skilled and dedicated workforce.
"We have to take this action but I remain convinced that we can make it through these difficult times and prosper again."
Employees in affected areas will meet with managers this week.
