Workers many have hoped to win (6)
I believe the answer is:
sweeps
'workers' is the definition.
(sweep is a kind of worker)
'hoped to win' is the wordplay.
'hoped' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'win' becomes 'sweep' (sweeping is a kind of winning).
's' after 'sweep' is 'SWEEPS'.
'many have' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for sweeps that I've seen before include "Clears with a brush" , "They clean chimneys with brushes" , "Cleans the floor with a brush" , "Cleans with a broom" , "Old blackguards" .)
