No, you are not allowed to work in Slovenia on a tourist visa. This visa is only meant for short visits such as tourism, meeting family or friends, or attending business meetings. It does not allow you to take up any job or earn money in Slovenia. If you want to work in Slovenia, you must apply for a proper work visa or a long-stay visa (Type D). It is important to follow visa rules, as working illegally can lead to fines or future visa issues.
