Worker on holiday, reportedly — one's pulled up at end of journey (9)
I believe the answer is:
handbrake
'one's pulled up at end of journey' is the definition.
(eg the handbrake in a car)
'worker on holiday reportedly' is the wordplay.
'worker' becomes 'hand' (hand is a kind of worker).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'holiday' becomes 'break' (break can mean a holiday or time off).
'reportedly' shows a homophone (sound like).
'break' sounds like 'brake'.
'hand'+'brake'='HANDBRAKE'
(Other definitions for handbrake that I've seen before include "It stops car" , "Manually operated device to hold vehicle" , "slower" .)
