Craftsman less inclined to work after midnight (7)
I believe the answer is:
glazier
'craftsman' is the definition.
(I know that glazier is a type of craftsman)
'less inclined to work after midnight' is the wordplay.
'less inclined to work' becomes 'lazier' (I've seen this before).
'after' means one lot of letters go next to another.
'midnight' becomes 'g' (the middle letter in 'night').
'lazier' after 'g' is 'GLAZIER'.
(Other definitions for glazier that I've seen before include "Glass cutter" , "Windowpane fitter" , "Window fitter" , "Workman" , "Window repairer" .)
