Steal from manager obviously (3)
I believe the answer is:
rob
'steal' is the definition.
(I know that rob is a type of steal)
'from manager obviously' is the wordplay.
'from' indicates a hidden word.
'ROB' is hidden within 'manager obviously'.
(Other definitions for rob that I've seen before include "Steal violently" , "sack" , "Steal or purloin" , "Steal from (someone)" , "Take without consent from the owner" .)
