As an HR expert, I understand your concerns about being asked to run personal errands as an intern in the marketing team. It is important to establish clear boundaries between personal tasks and professional responsibilities in the workplace. While your supervisor may have the authority to assign work tasks, it is reasonable for you to feel uncomfortable with being asked to handle personal matters like buying breakfast or picking up packages. Your role as an intern should primarily focus on learning and contributing to the marketing team's objectives. It is not unreasonable for you to assert your position and politely decline such requests in order to maintain a healthy balance between professional obligations and personal boundaries. You are absolutely right in not wanting to encourage an unhealthy hierarchical mindset. It would be appropriate to have a conversation with your supervisor and explain your perspective, emphasizing your eagerness to contribute to the marketing team's initiatives. By respectfully declining personal errands, you can redirect your energy towards tasks that align with your internship's objectives and avoid potential misunderstandings regarding your role. Remember, open and honest communication is crucial in establishing a positive work environment. It is always a good idea to discuss any concerns or discomfort with your supervisor or HR department so that they can address the issue and ensure a more suitable working arrangement for everyone involved. It is important for interns to feel valued and receive a meaningful learning experience during their time in the company.
