Teachers and pupils had to wear face masks as schools in Greece reopened on Monday (September 14).<br /><br />New COVID-19 guidelines insist teachers and pupils must wear a mask indoors as well as in outdoor spaces with high levels of crowding and school buses.<br /><br />A parent wearing a mask with a "resist to dictatorship" slogan written on it said: "I was forced to send my child to school wearing a mask, despite the fact I do not agree on that measure. Because my child suffers from allergies, I believe in a short space of time there will be many problems regarding mandatory mask use."<br /><br />The Deputy Mayor for Education of Thessaloniki, Dimitra Akritidou, said: "Τhe procedure must be followed as defined by the Ministry of Health, there is a health protocol for schools and the school principal is aware of this, if there are questions, information is available."<br /><br />Students will be sent home and marked as absent if they refuse to wear a face mask.
