Primark plans to move 220 jobs from its head office in Reading to the company’s international headquarters in Dublin.
The retail giant is moving its buying, merchandising, design, quality and sourcing operations to Ireland from September.
The company said the the decision was about “driving operational efficiency” and nothing to do with any external factors such as Brexit.
Employees affected by the changes will have the opportunity to work in Dublin.
Lorraine Culligan, group director of people and culture, said: “Our colleagues will be fully supported during this period of change.
“Primark’s office in Reading continues to play a vital role in our business
