Lacking in care (8)
I believe the answer is:
slipshod
'lacking in care' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for slipshod that I've seen before include "Careless in thought or organisation" , "Careless and slapdash, bad work" , "Disorganised" , "Inattentive" , "Lacking in care" .)
