What does 同事 mean?
同事 (tóngshì) is the standard noun for 'colleague' or 'coworker' — anyone you work with at the same company or organization, regardless of rank. Literally 'same-work,' it covers the full range that English splits between 'colleague' (slightly formal) and 'coworker' (casual). Unlike English, 同事 does not imply equal status: your boss and the intern are both your 同事 in a broad sense, though you'd normally call your boss 老板 / 领导 to their face.
同事 is used both in introductions ('这是我同事' — 'this is my colleague') and in third-person reference. The verb 'to be colleagues' is 是同事; 'to work together' is 一起工作. Don't confuse with 同学 ('classmate') or 朋友 ('friend') — Chinese keeps these social roles distinct more strictly than English.
