Workers at iconic biscuit company Tunnocks, which is based in Lanarkshire, Scotland, took two days of strike action this month after pay talks with bosses broke down.
Management made a renewed pay offer of 2% but workers decided to continue with the planned walkouts.
Unite regional organiser Derek Ormston said “The union is disappointed that the company has not approached us with an improved offer to avoid this action. Our members will be considering what the next stage will be once we have seen the result of the ballot on the 2% offer.”
Workers, who are already operating an overtime ban, will vote on the new deal by postal ballot due to close on 4 October.
