Satisfied to admit you and I worked hard (7)
I believe the answer is:
sweated
'worked hard' is the definition.
'satisfied to admit you and i' is the wordplay.
'satisfied' becomes 'sated' (I've seen this before).
'to admit' indicates putting letters inside.
'you and i' becomes 'we'.
'sated' placed around 'we' is 'SWEATED'.
(Other definitions for sweated that I've seen before include "Reacted to heat; exploited (labour)" , "(Of labour) ill treated and ill paid" .)
