I recently started my first job in public administration, and I'm feeling really frustrated about a situation with a colleague. I'm from a European country and this is my first role in the field. I consider myself a calm, polite, and kind person, but I think my naivety has led me to overlook some negative intentions from others. Unfortunately, I have a colleague who seems to have something against me for reasons I don't understand. After I finish my tasks, I sometimes scroll through my phone because there’s genuinely nothing else to do—no calls, emails, or files to process. However, this behavior was reported to my supervisor, resulting in a warning. I felt hurt by this because I would have appreciated direct feedback instead of being reported. Additionally, this colleague has been telling others that I'm overwhelming with my questions and that HR is hiring incompetent people. It's frustrating because I feel like I'm just trying to learn and do my job well. She appears friendly to my face, but her actions suggest otherwise. I’m still on probation, and my permanent hiring depends on her evaluation of my performance. This situation is really taking a toll on me.
