I work as a software developer in Germany and switched jobs six months ago. My new company is a small private company of 15 employees, with their own office building. I've worked there for half a year now and the boss told me that they are very satisfied with my work and me as a person. He told me, that I fit well into the company and everything is fine. We keep an open communication culture.
However, I still don't have free access to the office. All other employees, even two colleagues who were hired just two months ago, have their own digital access card. Each time I want to access the building, I have to ring and wait at the door and my colleagues have to open the door for me. I feel very uncomfortable about this, since they get interrupted from work every time. My boss knows that I have no keys, in fact he opened the door a few times himself.
Should I ask my boss why I still have no access, and when I will receive an access card? I'm not sure if this is considered rude or unprofessional, since my contract does not mention anything about access to the building.
