The Brief: A work spouse is a close friend at work.

DEEP DIVE
A work spouse, work wife, or work husband is a member of a close relationship between co-workers. While these terms generally describe friendly and platonic professional relationships, they can also be used in reference to romantic or sexual relationships between co-workers.
These terms of endearment are commonly used by millennials.
Question of the day are you allowed to have a work wife and a work husband or are you allowed only one? Because my work wife brings me coffee but my work husband gets me lunch

My work husband thought I was a rabid Red Sox fan. He even tried to give me a Red Sox book today. And does anyone know how to go about divorcing your work spouse?
