Argos delivery drivers are set to go on strike during the run-up to Christmas.
In a dispute over pay, the three-day walk-out looks set to threaten the delivery of goods in the days leading up to the festive holidays.
Members of Unite employed by Wincanton at a distribution centre in Staffordshire plan to walk out from next Tuesday.
The potential strike would end on December 22.
Unite is currently embroiled in a row over holiday back pay.
Regional officer Rick Coyle said: "The drivers have patiently tried to resolve this matter for over two years.
"Now they would like the money they are owed in time for Christmas, which is not unreasonable.
"It is very difficult to understand why Wincanton has allowed this saga to get out of hand because this strike by our members will cause havoc and mayhem to deliveries to Argos shops in the run-up to Christmas".
Mr Coyle added that the strike was only announced as a "last resort".
The news comes a day after the Post Office confirmed some of its workers would be staging a five-day strike next week - including Christmas Eve.
The Communication Workers Union is entangled in a long-running dispute over job losses, the closure of a final salary pension scheme and the franchising of Crown Post Offices.
