Company dismissed me over result (7)
I believe the answer is:
outcome
'result' is the definition.
(synonyms)
'company dismissed me over' is the wordplay.
'company' becomes 'co' (abbreviation).
'dismissed' becomes 'out' (I've seen this before).
'over' indicates putting letters inside.
'out'+'me'='outme'
'co' placed inside 'outme' is 'OUTCOME'.
(Other definitions for outcome that I've seen before include "answer" , "End result" , "Cute moo (anag.)" , "'Result, upshot (7)'" , "Eventuality" .)
