Short set of maps welcoming worker in Georgian city (7)
I believe the answer is:
atlanta
'georgian city' is the definition.
(city in the US state of Georgia)
'short set of maps welcoming worker' is the wordplay.
'short' means to remove the last letter.
'set of maps' becomes 'atlas' (book of maps).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'worker' becomes 'ant' (worker is a type of ant).
'atlas' with its final letter taken off is 'atla'.
'atla' enclosing 'ant' is 'ATLANTA'.
'in' acts as a link.
(Other definitions for atlanta that I've seen before include "one twinned with Tbilisi?" , "Maiden desperate to marry abandons a" , "City plundered and burned by Sherman's army, 1864" , "US place" , "City hosting the 1996 Olympics" .)
