Chopped down and fired (4)
I believe the answer is:
axed
I believe this clue is a double definition.
'chopped down' is the first definition.
(I've seen this before)
'fired' is the second definition.
(I've seen this in another clue)
'and' acts as a link.
(Other definitions for axed that I've seen before include "Dismissed with a hatchet" , "Stopped" , "Chopped or terminated" , "Dismissed, given the chop" , "Discontinued with hatchet?" .)
