Ordered ale for worker only rarely? (6)

I believe the answer is:

loafer

I'm a little stuck... Click here to teach me more about this clue!

'worker only rarely?' is the definition.
I can't judge whether this defines the answer.

'ordered ale for' is the wordplay.
'ordered' is an anagram indicator.
'ale'+'for'='alefor'
'alefor' with letters rearranged gives 'LOAFER'.

Can you help me to learn more?

(Other definitions for loafer that I've seen before include "one going on foot?" , "Lazy fellow or soft shoe" , "Fanciful baker" , "idle type" , "Idler; casual shoe" .)

I've seen this clue in The Times.
