In Trieste employees are treated with respect (6)
I believe the answer is:
esteem
'respect' is the definition.
(I've seen this before)
'in trieste employees are treated' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ESTEEM' is hidden in the letters of 'trieste employees treated'.
'with' is the link.
(Other definitions for esteem that I've seen before include "Favourable regard" , "Revere(nce)" , "Respect, admire" , "Value highly" , "Admiration, regard" .)
