Diageo Strike | Johnnie Walker’s Grain Distillery Votes to Walk Out

Johnnie Walker’s Grain Supply Just Voted to Strike

Workers at Cameronbridge, Europe’s largest grain distillery and the source of the whisky inside Johnnie Walker, have backed industrial action over job cuts. Unite says strike dates come within days. The timing, three months before Christmas, is not an accident.

There is a building in Fife that most whisky drinkers have never heard of and quietly depend on. Cameronbridge, near Leven, is Europe’s largest grain distillery. It employs around 200 people, and the single grain whisky it makes is the invisible majority of a blended Scotch: the component that makes Johnnie Walker taste like Johnnie Walker. It also produces spirit for Gordon’s, Smirnoff and Tanqueray. If Cameronbridge stops, a great deal stops with it.

On Wednesday, its workers voted to strike. Seventy-five per cent of GMB Scotland members backed industrial action on a 73% turnout, and more than 100 Unite members did the same, in what the union called an emphatic result. Unite’s general secretary Sharon Graham says strike dates will be announced within days unless Diageo returns to the table.

What Cameronbridge actually makes

This is the part that turns a local industrial dispute into a drinks story. Blended Scotch, which is the overwhelming majority of Scotch sold worldwide, is mostly grain whisky with malt whisky blended into it. The malts get the romance, the visitor centres and most of the space in my best whiskey guide. The grain does the volume, and Cameronbridge is where a very large share of Diageo’s grain comes from.

Unite’s industrial officer Dougie Orchardson has been explicit about what that means: “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.” That is a union making its leverage plain, and it is worth reading as such rather than as a forecast. But the leverage is real, and both sides know exactly what quarter of the calendar we are entering.

The argument

Diageo is roughly a year into a global restructuring under chief executive Sir Dave Lewis, aiming to strip $1 billion of costs over three years. Lewis has framed it as a “more agile, competitive and cost-effective operating model” that will return the company to consistently creating shareholder value. Scotland is carrying part of that, with hundreds of roles affected across its operations here.

The company’s position on Cameronbridge specifically is that this is a modest adjustment to reality. A Diageo spokesperson told the trade press: “We are in consultation with colleagues on proposed changes at Cameronbridge Distillery, which would see a small reduction in roles. While difficult, this follows the decision to maintain reduced production volumes to protect the long-term competitiveness of our business.”

The unions dispute both the process and the premise. Unite says Diageo has failed to consult properly and has offered “no explanation and minimal detail” on the redundancies. GMB Scotland’s Daniel Reid put it more bluntly: “The company came into these discussions with a plan already set in stone and no intention of seriously engaging with workers at risk of redundancy.”

And then there is the money. Unite points to Diageo Scotland’s most recent registered accounts, which show an after-tax profit of £595 million for 2025.

“Diageo is drinking in the last-chance saloon. Strikes will be announced in the coming days unless Diageo swiftly changes course. Diageo is raking in hundreds of millions of profit and there is no justification for slashing hundreds of jobs.”

The safety argument nobody is talking about

Buried under the headline numbers is the union claim I find most substantive, and it is not about pay or even really about jobs. Unite says the roles being cut include production operators and cask handlers, and that Diageo intends to maintain the same level of production with fewer of them.

If that is accurate, it is a workload question with a safety edge. A grain distillery is heavy industry: high-proof spirit, pressure vessels, heat, and cask handling that is genuinely physical work. Doing the same volume with a thinner crew is exactly the scenario safety regulators worry about. Diageo’s own framing points the other way, that this “follows the decision to maintain reduced production volumes,” which is a direct contradiction of the union’s account. Somebody is wrong about how much whisky Cameronbridge is going to make next year, and that is the disagreement worth watching.

The wider cuts, and a number worth checking

Cameronbridge is not isolated. GMB Scotland accused Diageo of “steam-rolling” through job cuts in August, when it reported that 172 distillery workers in the Highlands and Islands were at risk of redundancy. More recent coverage of the same dispute refers to 38 jobs at risk in the region.

Industrial action is also expected to affect other Diageo sites in Scotland, including the Leven and Shieldhall plants, both of which have been drawn into disputes with this workforce before. Anyone with a memory of 2019 will recall Leven, Cameronbridge and Shieldhall walking out together over pay, and 2016 before that over pensions. This is a workforce with form, and a company with a pattern.

Why this is happening now

Here is the context that makes the whole thing legible, and it is the story I have been writing about all year. Scotch has too much whisky. Around 1.4 billion litres is maturing in Scottish warehouses, roughly three years of global consumption, after a decade of building for growth that stopped arriving. Diageo has already paused production at Teaninich. LVMH halted Glenmorangie. Ian Macleod cut Glengoyne and Rosebank by 30%.

Cameronbridge is the same decision arriving at the other end of the business. When a company decides to make less whisky for several years, the people who make the whisky become, in the language of the restructuring deck, a cost line. Diageo says as much: reduced production volumes, long-term competitiveness. What the ballot represents is the first time in this cycle that the workforce has pushed back hard enough to threaten supply.

It is also happening while Diageo is fighting on other fronts. Its Canadian whisky business is navigating the US import prohibition that takes effect on 29 September, with Crown Royal apparently routed around it via bulk shipping and US bottling, a manoeuvre that required closing a Canadian bottling plant and moving that work south. A pattern is visible in both stories, and it is not a flattering one for anyone hoping big drinks companies feel much sentiment about where things get made. Nor is Diageo alone in restructuring around a market that has moved: Brown-Forman’s latest numbers show the same industry reading the same tea leaves, with cans growing 20% while its tequila fell 12%.

Will there actually be shortages?

Probably not the ones the headlines imply, and it is worth being calm about this. Blended Scotch is made from stock laid down years ago; nothing you drink this Christmas depends on what Cameronbridge distils this autumn. Diageo also holds enormous inventory and, as I keep pointing out, so does the entire industry. A short strike would not empty a shelf.

What a strike does threaten is bottling and packaging throughput, which is a far more immediate constraint, and the timing is the point. The run-up to Christmas is when volume matters most, which is precisely why the ballot has landed now and why Unite is talking about a standstill. That is not a coincidence; it is how industrial leverage works. If it runs for days, expect nothing. If it runs for weeks, expect gaps in specific lines rather than a whisky drought.

The last word

There is an uncomfortable symmetry here. For a decade the industry told us Scotch was scarce and precious, and priced it accordingly. Then it turned out the warehouses were full. Now the people who filled them are being told there is not enough work to go round, at a company whose Scottish arm cleared £595 million after tax last year, and they have voted to stop.

Whoever is right about the consultation, the substance is simple. Somebody has to absorb the cost of the industry making more whisky than the world wanted. So far that has been paused stills and quiet redundancies. This week, for the first time, it became a fight.

The whisky loch was made by decisions taken in boardrooms. The bill is being handed to Fife.

I will update this piece when strike dates are confirmed.
