Paddy, worker having drink after time (7)
I believe the answer is:
tantrum
'paddy' is the definition.
(thesaurus)
'worker having drink after time' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'having' says to put letters next to each other.
'drink' becomes 'rum' (I've seen this before**).
'after' says to put letters next to each other.
'time' becomes 't'.
'ant' put next to 'rum' is 'antrum'.
'antrum' put after 't' is 'TANTRUM'.
(Other definitions for tantrum that I've seen before include "Spoilt brat's fit" , "Uncontrolled outburst of anger" , "Hissy fit" , "Fit - pet" , "Burst of rage" .)
