The minimum wage is to increase by 30 cent to 9.55 an hour. The changes will come into place in January.
It works out as an increase of only 12 Euro a week for those working full time. The increase was one of the recommendations of the low pay commission.
Taoiseach Leo Varadkar says that gives businesses plenty of time to plan for the increase, but some groups are not happy.
Ibec, the group that represents Irish business, said that there is "no justification" for the increase. Director of Employer Relations, Maeve McElwee, argues that "any increase must be in line with economic realities."
She said the Irish minimum wage "is already one of the highest in the EU", and believes the rise will "be extremely difficult" for businesses to cope with.
