Lorry drivers at a Tesco distribution centre in South Yorkshire have rejected an offer to settle a dispute over possible job losses.
The union Unite said it meant further industrial action from its 180 driver members was possible.
The talks, which took place on Friday, ended in stalemate after the latest offer by haulage firm Eddie Stobart was rejected. It follows a 48-hour strike at the site in Doncaster earlier this month.
The drivers are angry at planned cuts to the haulage firm's operations at the site.
Eddie Stobart, which took over operations from Tesco at the site in August, announced the reorganisation in September.
Unite claimed that more than 180 lorry drivers' jobs at the Doncaster centre would be threatened if the plans went ahead.
