Lancashire-based brewers of Budweiser, Stella Artois, Becks, Boddingtons and Export Pale Ale are set to go on strike this summer over a pay dispute.
GMB Union has said a total of 225 of its members working at Budweiser Brewing Group's Samlesbury site will down tools on a series of dates next month.
It is the first time workers at the site have gone in strike in its 50-year history.
