Retired hotel employee, one with business abroad (8)
I believe the answer is:
exporter
'one with business abroad' is the definition.
(someone who exports to other countries)
'retired hotel employee' is the wordplay.
'retired' becomes 'ex' (prefix meaning former or onetime).
'hotel employee' becomes 'porter' (type of hotel employee).
'ex'+'porter'='EXPORTER'
(Other definitions for exporter that I've seen before include "one selling overseas" , "One selling abroad" , "One making foreign sales" , "Business that sells its goods abroad" , "One sending goods abroad" .)
