Quickest route to get worker in front of queue (7)
I believe the answer is:
beeline
'quickest route' is the definition.
'worker in front of queue' is the wordplay.
'worker' becomes 'bee' (I've seen this before**).
'in front of' is a charade indicator (letters next to each other).
'queue' becomes 'line' (I've seen this before).
'bee'+'line'='BEELINE'
'to get' is the link.
(Other definitions for beeline that I've seen before include "Make ........ for - go straight towards like honey collector" , "Direct track" , "Straight route" , "Shortest route between A and B" , "Straightest route" .)
