Cheer from employee finally out of office (5)
I believe the answer is:
elate
'cheer' is the definition.
(I've seen this in other clues)
'employee finally out of office' is the wordplay.
'finally' says to take the final letters.
'out of office' becomes 'late' (I've seen this in other clues).
The final letter of 'employee' is 'e'.
'e'+'late'='ELATE'
'from' acts as a link.
(Other definitions for elate that I've seen before include "Fill with joy" , "Exhilarate, put in high spirits" , "Make joyful and proud" , "Delight" , "Lift (the spirits)" .)
