Team leader requested to be assigned work (6)
I believe the answer is:
tasked
'assigned work' is the definition.
'tasked' can be an answer for 'assigned' (tasking is a kind of assigning). I am unsure of the 'work' bit.
'team leader requested' is the wordplay.
'leader' says to take the initial letters.
'requested' becomes 'asked' ('ask' can be a synonym of 'request').
The first letter of 'team' is 't'.
't'+'asked'='TASKED'
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for tasked that I've seen before include "Assigned a job to" , "charged" .)
