Tabloid workers featured in newspaper piece (8)
I believe the answer is:
fragment
'piece' is the definition.
(fragment is a kind of piece)
'tabloid workers featured in newspaper' is the wordplay.
'tabloid' becomes 'rag' ('rag' can be a synonym of 'tabloid').
'workers' becomes 'men' (man is a kind of worker).
'featured in' indicates putting letters inside.
'newspaper' becomes 'ft'.
'rag'+'men'='ragmen'
'ragmen' put inside 'ft' is 'FRAGMENT'.
(Other definitions for fragment that I've seen before include "Piece broken off something else" , "Incomplete part" , "Broken-off piece" , "Scrap" , "Shard" .)
