Employers' group Ibec has said there is no justification for increasing the national minimum wage from its current level of €8.65 per hour.

In a submission to be delivered at an Oireachtas Committee on Jobs, Enterprise and Innovation today, it warns that an excessive increase would jeopardise employment, new job creation, business investment and the viability of some firms.

Around 4.7% of the workforce is on the minimum wage of €8.65 per hour, according to the Central Statistics Office.

Ibec acknowledges that the minimum wage should increase as economic circumstances improve, but said it is already high by European standards, with its real value increasing since 2008.

It warns that an uncompetitive minimum wage will hurt not only employers, but also young and low-skilled workers, who could get trapped in long-term unemployment.

Employers argue that future decisions on the minimum wage level should factor in labour market conditions, international comparisons and competitiveness, sectoral and regional affordability, and cost of living trends.

They also raise concerns about attempts to implement a "living wage" at €11.43 per hour, given the different family circumstances and regional locations of individual workers.

Unions will inevitably take issue with Ibec's view, as they continue to seek pay rises for the lowest paid hardest hit by the recession.

Intense questioning by politicians is expected at the committee.
