technologists

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

'ghost in closet startled it workers' is the definition.
I can't judge whether this defines the answer.

'ghost in closet startled' is the wordplay.
'startled' indicates an anagram.
'ghost'+'in'+'closet'='ghostincloset'
'ghostincloset' anagrammed gives 'TECHNOLOGISTS'.

Can you help me to learn more?

(Another definition for technologists that I've seen is " Workers using applied science".)

I've seen this clue in The Sunday Times.
