Girl some in work are noticing (5)
I believe the answer is:
karen
'girl' is the definition.
'some in work are noticing' is the wordplay.
'some in' says the answer is hidden in the clue.
'KAREN' is hidden in the letters of 'work are noticing'.
(Other definitions for karen that I've seen before include "Girl" , "Girl's name - ethnic Thai in Burma" , "One at home in 15 across [AARHUS]" , "oriental language" , "Carpenter of note" .)
