I think maybe a breakaway thread should be set up entitled 'Public Sector sick leave'.
To go slightly back on point, I think the media will often extract juicy headlines from reports without providing any proper analysis. For instance, I know very few Public Servants who take an average of 16 sick days a year. I do, however, know of a small number of lazy, dishonest parasites who take far, far more than that every year. Therefore, the 'average' Public Servant is not taking 16 days sick leave annually, but 'a very small number' of Public Servants are taking vastly excessive amounts of sick days per annum.
Likewise, there are some very unscrupulous employers in the Private Sector who totally ignore their employees rights, treat migrant workers like dirt and bully vulnerable workers. In these cases the employees would not dare take sick leave unless they were at death's door. They are not 'average' private sector employees but they are skewing the figure downwards.
The use of the word 'average' is often used by the media to perpetuate myths.
