Question Time with head of state about jobs (5)
I believe the answer is:
tasks
'jobs' is the definition.
('task' can be a synonym of 'job')
'question time with head of state about' is the wordplay.
'question' becomes 'ask' (**).
'time' becomes 't'.
'with' means one lot of letters go next to another.
'head of' indicates taking the first letters.
'about' indicates putting letters inside.
The initial letter of 'state' is 's'.
't'+'s'='ts'
'ask' put inside 'ts' is 'TASKS'.
(Other definitions for tasks that I've seen before include "Chores, undertakings" , "Chores, jobs" , "charges" , "Assignments" , "Pieces of work" .)
