Tend to back employees running shows (5)
I believe the answer is:
nurse
'tend to' is the definition.
(I've seen this in another clue)
'back employees running shows' is the wordplay.
'back' says the letters should be written backwards.
'shows' says the answer is hidden in the clue.
'esrun' is hidden within 'employees running'.
'esrun' in reverse letter order is 'NURSE'.
(Other definitions for nurse that I've seen before include "Entangle" , "Trained carer" , "care worker" , "drink slowly" , "Hospital carer" .)
