Final answer:
Most companies expect employees to handle simple maintenance tasks like changing out a light, but more complex tasks are usually handled by professionals.
Step-by-step explanation:
Your responsibilities when it comes to actual maintenance will depend on your company's policy. Most companies expect you to fix simple problems such as changing out a light but do not expect or want you to make other repairs such as performing an engine tune-up, replacing the brake line, or aligning the wheels. These latter tasks typically require specialized skills and training, and conducting such repairs may pose safety risks if not done properly. Therefore, they are often handled by professionals in those specific areas.
