French public-sector workers take an average of nearly a month off beyond annual leave, according to a report.

French public spending is among the highest in the world and due to hit 57 percent of national output this year. State workers make up one-fifth of France's total employed ranks and their salaries account for a quarter of public expenditure.

A report by civil society think tank iFRAP found that local public workers in cities of over 100,000 residents, excluding Paris, missed nearly a month of work on average per year on top of holidays — over double the rate in the private sector. The study calculated public servants in 25 cities missed an average of 26 days per year, or 12 percent of total work days.
