More than 200 jobs are to go at Cadbury in a move the company says will safeguard production at Bournville for the next 25 years, according to reports.
It will see long serving members of staff receiving payoffs of more than £100,000.
Cadbury say none of the job losses will be compulsory.
The American food giant that owns Cadbury is facing strong criticism for 'secretly' rolling out a new 'cheap-tasting' Creme Egg.
Chocolate maker Cadbury has recalled two of its products after traces of pig DNA were found in the hazelnut and roast almond bars during testing for non-halal substances in Malaysia.
Many Muslims have reacted with anger and some Islamist groups even called for “jihad” against the company for what they call a “betrayal", according to AFP.
"Cadbury has voluntarily removed two of its products from the shelves," said the Malaysian health minister, S Subramaniam.
Some chocolate bars have been taken off the shelves in Shah Alam, outside Kuala Lumpur, in Malaysia.
