Woman’s not spotted saving uniform for such labours? (9)

I believe the answer is:

herculean

I'm a little stuck... Click here to teach me more about this clue!

'for such labours?' is the definition.
I can't judge whether this defines the answer.

'woman's not spotted saving uniform' is the wordplay.
'woman's' becomes 'her' (belonging to a woman).
'not spotted' becomes 'clean' (I've seen this before).
'saving' means one lot of letters goes inside another.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'clean' enclosing 'u' is 'culean'.
'her'+'culean'='HERCULEAN'

Can you help me to learn more?

(Other definitions for herculean that I've seen before include "Old Labour" , "So enormous a task" , "for Poirot?" , "Monumental (task)" , "Powerful" .)
