A statement resonated for a long time with Sandra, whose actual name is different. “You have nothing to do now anyway,” a doctor told her once in August. Sandra is a primary school teacher and she had the doctor’s appointment during her summer holidays. And actually she knows such comments all too well. But she simply couldn’t get this specific sentence out of her head, she says. Because: Officially the 28-year-old was still free, unofficially preparations for the new school year had long since begun. “You always hear that you have so much vacation and have to work so few hours. That’s very stressful,” she says.
