Greatly resented being worked to death (5)
I believe the answer is:
hated
'greatly resented' is the definition.
'hated' can be an answer for 'resented' (I've seen this in another clue). I'm not certain of the 'greatly' bit.
'worked to death' is the wordplay.
'worked' is an anagram indicator.
'death' with letters rearranged gives 'HATED'.
'being' is the link.
Can you help me to learn more?
(Other definitions for hated that I've seen before include "couldn't stand" , "was unable to stand" , "Abominated" , "Heartily disliked" , "Detested" .)
