Which option is NOT a method for scheduling labor?

The reason an employee performance record is not a method for scheduling labor lies in its purpose and function. An employee performance record primarily serves as a tool for evaluating and documenting an employee’s work performance, achievements, skills, and areas for improvement. While this information can be relevant for making decisions about promotions, raises, or training, it does not directly aid in the scheduling of labor.

In contrast, the other options directly relate to scheduling tasks and managing labor resources. A calendar with a shift provides a framework for determining when employees are available to work, while a job assignment listing outlines specific tasks assigned to each employee during a given time. A work plan details the overall approach to completing a project, including labor requirements and timelines, thus facilitating effective scheduling. Understanding the role each option plays helps clarify how they either assist with labor scheduling or focus on performance evaluation.
