Worker given cards worried many (8)
I believe the answer is:
handyman
'worker' is the definition.
(handyman is a kind of worker)
'cards worried many' is the wordplay.
'cards' becomes 'hand' (I've seen this in other clues).
'worried' indicates an anagram.
'many' with letters rearranged gives 'yman'.
'hand'+'yman'='HANDYMAN'
'given' is the link.
(Other definitions for handyman that I've seen before include "Odd-jobs person" , "One employed to do odd jobs" , "One hired to do odd jobs" , "Jack-of-all-trades" , "Repairer" .)
