Which of the following methods cannot be used to recruit workers from outside a facility?

A career ladder is a system used within an organization to promote employees through various levels of advancement based on their skills, experience, and performance. Essentially, it focuses on nurturing and developing talent from within the organization rather than seeking new talent externally. This method is inherently about internal growth and succession planning, meaning it cannot be used to recruit workers from outside the facility.

In contrast, job fairs and networking are both proactive methods aimed at attracting external candidates. Job fairs provide a platform where employers can engage with potential workers directly, while networking involves leveraging professional connections to identify and attract talent from outside the organization. Internal promotions also rely solely on existing employees moving up in their current roles, which does not involve bringing in new applicants from outside the company.
