Telecoms company Vodafone is to cut 11,000 jobs over the next three years.
Its new group chief executive, Margherita Della Valle, has criticised the firm's performance as 'not good enough' as it announced full-year results.
Vodafone has yet to respond to requests for information on how many Irish roles could be affected.
Ms Della Valle was appointed CEO last month after her predecessor Nick Read was ousted late last year.
On Tuesday, she said: "Our performance has not been good enough. To consistently deliver, Vodafone must change.
"My priorities are customers, simplicity and growth. We will simplify our organisation, cutting out complexity to regain our competitiveness.
"We will reallocate resources to deliver the quality service our customers expect and drive further growth from the unique position of Vodafone Business," she added.
She was speaking as Vodafone reported a 1.3% drop in full-year earnings to stg£12.8 billion (€14.71bn).
It said group service revenue was impacted by a decline in Germany, Italy and Spain.
However this was offset by continued growth in Ireland, Portugal, Greece, Romania, the Czech Republic, Albania, the UK and Africa.
In Ireland, it said the service revenue increase was driven by customer base growth, higher roaming revenue and contractual price increases.
Its mobile contract customer base here increased by 64,000 and it saw its broadband base also grow by 14,000.
In October last year, Vodafone Ireland announced a fixed wholesale network access agreement with Virgin Media.
"Vodafone is already the largest fibre-to-the home provider in Ireland, covering over one million households," the company said.
Other markets came in for criticism with Germany, its largest, remaining "under pressure" as service revenue growth fell by 1.6%.
A "strategic review" of the business is also to be carried out in Spain.
