Strikes are to be staged by brewers of Budweiser, Stella Artois, Becks, Boddingtons and Export Pale Ale in Lancashire after crisis talks collapsed.
Union GMB said its members at the Samlesbury site in Lancashire will take part in a 36-hour walk out from Saturday, July 16, with a further 12-hour stoppage on Tuesday, July 19.
Budweiser Brewing Group said it has "a positive and long-standing relationship with the GMB, however despite open negotiations, the GMB have confirmed that there will be additional dates for industrial action at our Samlesbury brewery".
