What method involves the employer providing notices of job openings, to which employees respond by applying?

The method that involves the employer providing notices of job openings, encouraging employees to respond by applying, is accurately identified as job posting.

Job posting is a systematic approach where an organization communicates available positions internally, often through company intranet portals, bulletin boards, or internal emails. This allows existing employees not only to be informed about available opportunities but also to express their interest in advancing their careers within the company.

This internal recruitment technique can enhance employee morale by demonstrating that the organization values internal mobility and career development. It can also save time and resources, as it often leads to quicker placements than external recruiting efforts.

In contrast, other options like job listings and job advertisements typically refer to public or external-facing methods where positions are advertised to a broader audience. A job board specifically entails a platform where these listings can be posted, but the term does not define the action of notifying current employees directly.
