Happening or existing after someone has retired from their job or profession.

Postretirement → It is formed from "post-" (meaning after) and "retirement" (from Latin "retirare", meaning to withdraw). The word refers to the period or activities that occur after one has withdrawn from their professional career.
Think of 'post-' meaning 'after' and 'retirement' as the time when someone withdraws from work — so postretirement is what happens after someone has stopped working.
