Chided solemn nurses at centre, calling them layabouts (6)

I believe the answer is:

idlers

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

'layabouts' is the definition.
('idler' can be a synonym of 'layabout')

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for idlers that I've seen before include "The work-shy?" , "They're not inclined to work" , "They hang about doing nothing" , "Lazy people, layabouts" , "Loafers, time wasters" .)

I've seen this clue in The Irish Times.
