Hack concerned with one who handles things in hotels (8)
I believe the answer is:
reporter
'hack' is the definition.
(I've seen this before)
'concerned with one who handles things in hotels' is the wordplay.
'concerned with' becomes 're'.
'one who handles things in hotels' becomes 'porter'.
're'+'porter'='REPORTER'
(Other definitions for reporter that I've seen before include "One gives us the news" , "News gatherer" , "Hack" , "One writing in newspaper" , "One may get a story" .)
