co-worker

Fellow staff member

A co-worker is someone you work with—a colleague at your job or on a project.

The term is neutral and common in workplace contexts: I'm grabbing lunch with a co-worker.

It implies shared employment rather than hierarchy; your boss isn't typically called a co-worker.

Also spelled coworker.
