Idler upset and irritated (5)

I believe the answer is:

riled

'irritated' is the definition.
(I know that irritated can be written as riled)

'idler upset' is the wordplay.
'upset' is an anagram indicator.
'idler' anagrammed gives 'RILED'.

'and' acts as a link.

(Other definitions for riled that I've seen before include "Made angry" , "Vexed" , "Nettled" , "get angry" , "Irritated, provoked" .)

I've seen this clue in The Globe and Mail.
