Eir has said it intends to further reduce the company's gender pay gap, after a report revealed the difference in the hourly wage of men and women.
An 11.2% gender pay gap was identified for last year, which the company pointed out is 2.7% lower than the national average.
The company said a number of factors contribute to this gap and that it is working "urgently" to improve the situation.
The company said that a higher percentage of male employees work in specialised engineering roles, building and maintaining the physical and IT networks, with an average tenure of nearly 30 years, which contributes to higher salaries.
It said another contributing factor is that almost 60% of female employees work in customer facing roles with typically lower lengths of service and a comparatively lower salary.
According to the Eir report, the overall gender pay gap does not affect all parts of the organisation and in many areas of the business there is pay parity, including customer operations and senior management.
Eir is led by a female CEO, Carolan Lennon, who said she is proud that the company is led by a management team made up equally of women and men.
"This is a management team which values diversity and understands that an inclusive organisation, which really values differing viewpoints and skillsets, delivers real and tangible business benefits.
Ms Lennon said the company is publishing this gender pay gap report to show how important it feels this issue is.
"We continue to embed actions that are aimed at increasing the gender balance and culture of diversity and inclusion in the workplace, and by extension reducing our gender pay gap."
The Eir report shows that males account for 80% of staff at the company, with just 20% female.
The number of new women hires has increased from 30% in 2016, to 37% in 2020.
