Figures compiled for the public spending watchdog Audit Scotland revealed that there have been almost two million days lost at local authorities in the past year.
It estimates that 9000 employees, including 1800 teachers out of Scotland's 250,000 local government staff are calling in for time off due to illness each day.
Council workers averaged just over 11 days off in 2012/13, more than double the figure of just over five days in the private sector.
The average absence rate for teachers was, lower at just under seven days.
But they work 190 days a year compared to around 225 for other occupations.
Absenteeism among council workers and teachers combined has gone up by around 7% in the past year.
Based on the average salary for a public sector employee of £28,800, the sick note culture costs taxpayers more than £220 million a year.
Stress, depression, back problems and colds are among the most common reasons cited for absences.
The figures for Audit Scotland show the smallest local authority, Clackmannanshire, had the highest sickness rate. It was followed by East Dunbartonshire, West Dunbartonshire, Aberdeen City and Fife. The lowest rate was in Orkney.
Dave Watson, of the public sector workers' union Unison claimed the rise was a consequence of job cuts.
He said: "We have carried out surveys and found sickness had gone up in areas where jobs had been cut but there had been no reduction in workloads. Those left behind have to plug the gaps, resulting in increased levels of stress."
