Semi redeveloped, shadily covering over breaks (4-8)

I believe the answer is:

half-holidays

'breaks' is the definition.
(type of break or vacation)

'semi redeveloped shadily covering over' is the wordplay.
'semi' becomes 'half' ('semi' means 'half').
'redeveloped' indicates anagramming the letters.
'covering' says to put letters next to each other (on top of in down clue).
'over' becomes 'o' (cricket abbreviation).
'shadily'+'o'='shadilyo'
'shadilyo' anagrammed gives 'holidays'.
'half'+'holidays'='HALF-HOLIDAYS'

I've seen this clue in The Telegraph.
