Explosive tape shows workplace with poor conditions (9)
I believe the answer is:
sweatshop
'workplace with poor conditions' is the definition.
'explosive tape shows' is the wordplay.
'explosive' indicates an anagram.
'tape'+'shows'='tapeshows'
'tapeshows' anagrammed gives 'SWEATSHOP'.
(Other definitions for sweatshop that I've seen before include "Factory with low pay and long working hours" , "cheap workplace" , "where work is hard" , "Place where long hours are worked for low pay" , "Place employing exploited workers" .)
