If no one is in the office, what must be posted outside?

Posting a sign indicating the recruiter return time and the RINC's government-issued cell phone number outside the office is essential for maintaining transparency and accessibility for potential recruits. This approach ensures that individuals who visit the office know when to expect the recruiter back, minimizing confusion and potential frustration. Additionally, providing the RINC's government-issued cell phone number allows individuals to reach out for assistance or inquiries while the office is unstaffed, thereby offering a direct line of communication and fostering a welcoming environment.

Providing a note that states the office is temporarily closed does not convey useful information about when it will reopen or how to get immediate assistance. Similarly, directing people to the nearest Navy office or listing available recruiters in the vicinity may not effectively address the immediate needs of individuals seeking information or assistance from the specific office in question. Thus, the chosen answer prioritizes maintaining communication and service continuity for those who may require immediate support.
