Questions & Answers about Бывший сотрудник теперь работает здесь.
Бывший means former or ex- when talking about a person’s previous role, position, or relationship.
So:
- бывший сотрудник = former employee
- бывший муж = ex-husband
You usually use бывший for something that someone used to be, but is not anymore.
By contrast, прошлый usually means last or previous in a more general sense:
- прошлый год = last year
- прошлая неделя = last week
So прошлый сотрудник would sound wrong for former employee in this context.
It is in the nominative singular, because it is the subject of the sentence.
The sentence answers the question Who works here now?
- бывший сотрудник = the subject
- теперь работает = now works
- здесь = here
Since Russian marks grammatical roles with case, the subject normally appears in the nominative case.
