What does the “marginal” category of work generally imply?

The "marginal" category of work typically indicates a level of performance that is below the average. This classification suggests that the individual or work output does not meet the standard expectations typically associated with higher levels of competence. In many professional settings, being categorized as marginal may reflect a range of concerns, such as insufficient skills, inadequate training, or a lack of experience needed to perform tasks effectively. This distinction is critical in training and development contexts, as it highlights areas needing improvement and focuses on helping individuals to enhance their capabilities to move toward average or above-average performance levels. It is important in understanding how workers can be supported to develop the skills required to succeed in their roles.
