Responsible for factory worker being late (10)
I believe the answer is:
behindhand
'late' is the definition.
(thesaurus)
'responsible for factory worker' is the wordplay.
'responsible for' becomes 'behind' (I've seen this before).
'factory worker' becomes 'hand' (I've seen this in other clues).
'behind'+'hand'='BEHINDHAND'
'being' acts as a link.
(Other definitions for behindhand that I've seen before include "Late or slow in doing something" , "not keeping up with schedule" , "From which one might snigger" , "in debt" , "Late - in arrears" .)
