When you're making introductions, and, say, your entire team is present, show deference to your boss and other higher-ups by introducing them to your partner first.
"Avoid gender bias with introductions despite that this has been done historically," Feuerman said.
If a coworker is on an equal level as you, then start with your significant other. For example: "Jane, I'd like you to meet John, who works in the cubicle next to mine. John, this is my wife, Jane."
