Retiring from the company by the end of July (3)
I believe the answer is:
coy
'retiring' is the definition.
(both can mean shy)
'company by the end of july' is the wordplay.
'company' becomes 'co' (abbreviation).
'by' says to put letters next to each other.
'the end of' indicates one should take the final letters.
The last letter of 'july' is 'y'.
'co'+'y'='COY'
'from the' is the link.
(Other definitions for coy that I've seen before include "Military team in brief" , "Pretending shyness" , "Pretending to be shy or embarrassed" , "Reserved" , "not forthcoming" .)
