Holding a telephone conference call is particularly efficient for employees who work in different cities because it allows them to connect and communicate in real-time despite geographical barriers. This mode of communication eliminates the need for travel, making it a cost-effective and time-saving option. Employees can share ideas, discuss projects, and collaborate without being physically present in the same location. This is especially relevant in today's work environment where remote work and distributed teams are increasingly common.

While the other options may present valid scenarios for employee communication, they do not specifically highlight the primary benefit of a telephone conference call, which is to connect individuals separated by distance. For instance, requiring visual aids for discussion would be better served through video conferencing tools rather than a telephone call, which lacks visual components. Performing different job functions does not inherently necessitate a conference call, as employees could communicate via other methods like email. The option regarding text messaging capabilities doesn’t relate to the benefits of a telephone conference call, as the latter is not dependent on messaging capabilities at all. Therefore, the situation of working in different cities best captures the primary utility of a telephone conference call.
