Centres incorporating hotel jobs (6)
I believe the answer is:
chores
'jobs' is the definition.
('chore' can be a synonym of 'job')
'centres incorporating hotel' is the wordplay.
'centres' becomes 'cores' (core is a kind of centre).
'incorporating' indicates putting letters inside.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'cores' enclosing 'h' is 'CHORES'.
(Other definitions for chores that I've seen before include "Routine or daily tasks" , "Specific tasks to be done" , "Routine or household tasks" , "Routine or tedious tasks" , "Routine jobs or tasks" .)
