Hewlett-Packard is to cut another 25,000-30,000 jobs in its enterprise business due to falling demand for products.
The latest wave of cuts come on top of the 55,000 layoffs previously announced by the company's chief executive Meg Whitman.
HP has around 4,000 employees in Ireland working in manufacturing, research and development, customer software support, marketing, and sales and services.
The majority are based in Leixlip, Co Kildare with other operations in Galway and Dublin's Swords.
The company indicated the cuts announced today will be global, but provided no specifics so it is not yet known whether its Irish operations will be affected.
Once the biggest computer company in the world, HP has spent the last few years trying to get to grips with falling demand for personal computers and the move to cloud computing.
The firm is planning to split into two in November, creating one company - Hewlett Packard Enterprise which will focus on corporate hardware and services operations and another - HP Inc - to focus on its PC and printer businesses.
