Re-trenched

Someone close to me made an announcement the other day:  “I’ve been retrenched”.  There is something about this word that gets to me.  Root word:  trench.  Like trench warfare, World War I.  Fighting in the trenches, all that mud, dirty water, rats, gangrene.  And to be “re-trenched” sounds like you have to go through with it all over again.  Nobody ever said work is easy.  At times, you really are waging a war.
