New figures from the Central Statistics Office (CSO) have revealed which sectors can expect to clock in the most working hours.
According to the CSO, those working in farming, fishery and forestry sectors can rack up an average of 49.1 hours a week.
Its review of employment data for the last six years also showed the average working week in Ireland is 35.8 hours.
Among those who run up the lowest numbers for a five-day working week are teachers and others in the education sector, who clock up an average of 29.4 hours.
Sales and customer service staff also run up low weekly averages of 29.9 hours.
The CSO said the country's 325,500 self-employed workers also ranked high on the longest days with an average working week of 44 hours, while managers, directors and senior officials clocked up 43 hours a week.
Its six-year review of data from the Quarterly National Household Survey also showed job creation has been growing steadily in Ireland for the last four years with 1,976,500 people now employed.
The number of people in work increased by 46,900 or 2.4% over the 12 months to the end of March 2016 and that annual employment growth was around the 40,000 mark in both 2014 and 2015.
The review also revealed that almost one third of the country's 456,200 part-time workers claimed they could not find full-time work.
