The average civil servant took 10.1 sick days last year, according to new official figures.
The Department of Public Expenditure and Reform says that is a slight fall from 10.3 days in 2013.
Meanwhile, workers across the public service took an average of 8.7 sick days - down from 9.1 sick days a year earlier.
The Department says sick leave across the entire public sector has fallen, saving the Government around €100m last year.
