Go back into – or out of – employment (6)

I believe the answer is:

resign

'go back into or out of employment' is the definition.
(sign contract again or voluntarily leave job)

This is all the clue.

(Other definitions for resign that I've seen before include "Give up one's job" , "Quit" , "Give up one's post" , "surrender" , "Stand down" .)

I've seen this clue in The Everyman puzzle in The Observer.
