Irn-Bru producer AG Barr said it believed it had made a fair and competitive pay offer to its drivers and so it was ‘disappointed’ that 11 have now gone out on strike at its Cumbernauld depot.
It added that contingency plans were in place to avoid disruption to its services.
The Unite union claimed the soft drinks company had offered a real terms pay cut to its trucker and shunter drivers and strikes will take place between now and 6 October.
A continuous ban on overtime also came into effect this week.
Talks took place via ACAS but the union said AG Barr had refused to move beyond a 5% pay offer to drivers this year.
