Everyone in the staff picked up money (6)
I believe the answer is:
dollar
'money' is the definition.
(US currency)
'everyone in the staff picked up' is the wordplay.
'everyone' becomes 'all' (all people).
'in the' means one lot of letters goes inside another.
'staff' becomes 'rod' (both can mean a stick or cane).
'picked up' is a reversal indicator.
'all' inserted inside 'rod' is 'rallod'.
'rallod' backwards is 'DOLLAR'.
(Other definitions for dollar that I've seen before include "Australian currency" , "US monetary unit" , "100 cents" , "American currency" , "One hundred cents" .)
