IRN-BRU supplies are under threat as workers have voted to strike.

Unite the Union announced today that strike dates are set to hit the A.G. Barr's production and distribution centre in Cumbernauld following a pay dispute.

The union confirmed that its trucker and shunter drivers, who are essential to the supply of the company's products, will strike in a series of 24-hour stoppages.

Nine days of strike action will begin on Friday, August 11, with the final stoppage being on Friday, October 6. 

A continuous ban on overtime is also set to begin on Tuesday, August 8. 

A.G. Barr workers previously backed the strike action by 83%. 

It comes after Unite and A.G. Barr failed to reach an agreement over pay, with the company offering a 5% pay increase. 

The union says the offer equates to a real terms pay cut.

Sharon Graham, Unite general secretary, said: "Supplies of Irn-Bru could dry up in a few weeks due to the key role our members carry out for A.G. Barr.

"The company is cash rich with £52.9m chilling in the bank.

"Yet, they are offering our members a significant real terms pay cut when they can easily afford to pay more.

"We will back our members all the way in their fight for better jobs, pay and conditions."

Andy Brown, Unite industrial officer, added: "Despite our best efforts to resolve this dispute through negotiation, A.G. Barr has not moved beyond 5%.

"The only way it seems they will pay attention is if supplies of its popular products including Irn-Bru start to fizzle out which is exactly what is now on the cards."

A spokesperson for A.G. Barr said: "We’re disappointed in the decision by around 10 of our Scottish-based HGV1 drivers to take industrial action. 

"We made an offer that we believe is fair and competitive - in line with what has been agreed with our other employees. 

"We believe we have a responsibility to be fair to everyone.  

"We have contingency plans in place to maintain customer service and we will continue to work with Unite representatives and ACAS to find a positive and constructive resolution."
