To help the trainee gain experiences in all service demands, they should be:

The most effective way to ensure that a trainee gains diverse experiences in handling all service demands is to place them on a rotation schedule of assignments. This approach allows the trainee to encounter a variety of situations and scenarios across multiple areas of the operation, which enhances their adaptability and problem-solving skills.

By rotating through different assignments, the trainee becomes familiar with various aspects of the job and different team dynamics, allowing them to experience the full spectrum of challenges that may arise. This hands-on exposure is invaluable for developing a well-rounded skill set that is essential in a fast-paced environment.

In contrast, having a mentor can provide guidance and support, but it may not necessarily expose the trainee to the full range of service demands. A fixed shift assignment and a restriction to day shifts limit their exposure to the variety of calls and situations that can occur during different times of the day or night, which can hinder their ability to develop comprehensive skills. Therefore, a rotation schedule is the most effective approach to achieving the goal of diverse experiences.
