Unite members voted on industrial action last month, with the union now confirming staff will down tools in the near future.
Strike dates are expected to be announced in the coming days. Unite previously indicated industrial action could begin by mid-September.
The dispute centres on Diageo’s plans to axe around 10 jobs at the site, following a global restructuring programme.
Unite general secretary Sharon Graham said: “Diageo is drinking in the last chance saloon. Strikes will be announced in the coming days unless Diageo swiftly changes course.
Job cuts
“Diageo is raking in hundreds of millions of profit and there is no justification for slashing hundreds of jobs across its operations.”
Cameronbridge, Europe’s largest grain distillery, employs around 200 people, with some 70 roles currently under review.
Unite claimed Diageo failed to properly consult workers over the proposed job cuts at Cameronbridge, alleging the company provided little detail or explanation about the redundancies.
The union also raised concerns about worker safety and wellbeing, particularly among production operators and cask handlers, arguing staffing reductions are being proposed despite no corresponding cut to production levels.
However, a spokesperson for Diageo rejected the claims.
They told The Morning Advertiser (The MA): “We are disappointed by the outcome of the ballot and remain committed to engaging constructively.
“The proposed changes are necessary as we maintain reduced production volumes to protect the long-term competitiveness of our business.”
Difficult decision
The MA understands Diageo has planned to maintain lower levels of grain distillation at the site over the next few years following the cuts.
Diageo employs around 3,000 people across distilleries and bottling plants in Scotland.
The company’s latest accounts show Diageo Scotland recorded an after-tax profit of £595m in 2025, following a £736m profit in 2024.
Cameronbridge produces a number of major brands, including Johnnie Walker, Smirnoff and Tanqueray.
Unite industrial officer Dougie Orchardson added: “Diageo need to listen to its workers or the distillery will be brought to a standstill.
“Industrial action will inevitably result in supplies and shortages of many people’s favourite drinks. This is directly a result of Diageo planning to boost profits at the expense of its loyal workforce.”
