Two hundred workers at Cadbury’s Marlbrook plant, near Leominster, are waiting to hear about their futures after Tuesday’s announcement of the £11.5 billion takeover by US food giants Kraft.
The Cadbury board was advising shareholders to accept the package.
Unite union representatives have fought a long battle against the move and up until Saturday were collecting signatures from shoppers in Leominster town centre.
Marlbrook, which was opened in 1936, produces chocolate crunch and employs 120 staff and 80 contract workers.
Cadbury has been an independent producer of chocolates for nearly 200 years since its first beginnings in Bournville, Birmingham.
Unite has voiced fears that jobs will move abroad and the iconic brand’s reputation will be lost.
Producing the raw materials for chocolate making, Marlbrook is the only plant of its kind in the country and its loss would be a blow to local farmers and suppliers.
Cadbury were holding out for £8.50 per share with outer suitors waiting in the wings, including Hershey and hedge fund investors.
The company has issued trading figures for 2010 forecasting sales growth up to 7 per cent and a 10 per cent rise in dividend.
