co-workers with benefits 

This is similar to friends with benefits with a spin on it. It refers to the people who work together and hook up. They aren't in a serious relationship with each other, they only use each other for sex. And if they are married, not to each other, even better.

In the movie, Secretary, the character played by James Spader and the character played by Maggie Gyllenhall were co-workers with benefits.

Ex-Coworker with Benefits 

Like friends with benefits but between two people who were previously coworkers. Also known as ECWB.

Not to be confused with Coworkers with Benefits

“Hey Ashley, since we matched on Hinge, would that make us ECWB if we banged?”

“ECWB? What’s that?”

“Ex-Coworker with Benefits, obviously. It’s a new lingo.”
