Empty classroom syndrome. Many teachers out on sick leaves in protest

Not only employees of the judicial system are asking for raises, as teachers are also requesting 1,000 zlotys more. Many of them went on sick leaves in protest against low wages. The employers are sending requests to the Social Insurance Institution (ZUS) for controls of sick leaves of some teachers. It's our duty to respond to each of the notifications, says the ZUS spokesman Wojciech Andrusiewicz.
