Coca-Cola staff are to protest against restructuring plans which they say will lead to lower pay and jobs put at risk.
Members of the Unite union at Sidcup, Bristol, East Kilbride, Northampton, Wakefield, Milton Keynes and Edmonton in London will hold protests.
Unite says the company is using the economic climate to force through "attacks on jobs and pay".
But the firm says it is seeking a "consistent way of working" across its UK, Belgian, Dutch and French plants.
Unite's national officer Jennie Formby said: "We are extremely concerned that a recession-resistant company seems bent on using the economic difficulties to force through attacks on jobs and pay."
She said there must be a guarantee of "no compulsory redundancies, permanent pay protection for all displaced workers and Coke must start to engage fully in meaningful consultation".
Ms Formby said union members should not pay the price "for changes that will further benefit this phenomenally profitable company".
But a spokesman for Coca-Cola Enterprises said it was "proposing to make changes at our manufacturing and distribution sites in Britain".
He added: "These changes target a single, consistent way of working across all our plants in Britain, Belgium, The Netherlands and France, so that we can remain competitive and grow our business for the future."
He said the proposed changes could mean 120 roles being cut in the UK, but that 130 new posts "and other development opportunities would also be created".
