About 250 Northern Ireland bakery workers are set to strike on Sunday.
Talks between Allied Bakeries and the trade union Unite broke down on Friday.
Allied Bakeries is best known in Northern Ireland for brands like Kingsmill and Sunblest.
It is owned by Associated British Foods – an international company that owns a range of brands across different sectors, including Primark, and posted pre-tax profits of around £1.4bn last year.
But according to its latest accounts, Allied Bakeries was operating at a loss, which had been reduced because of cost-cutting measures.
The accounts also indicated lower reported sales.
