While we try to keep our work and personal lives separate for the most part, sometimes one creeps into the other. If you're unsure of how to handle making personal phone calls during the workday, then take a page from your officemates. It may be A-OK to make a call from your desk, but if you need privacy, then ducking into an empty conference room for a quick call might be more appropriate. Some offices have designated phone rooms for this purpose, or you could find yourself out in the hallway or on the street. And make note of whether your coworkers are using their company-paid desk phones or their personal cell phones to make personal calls too.
