View workers abandoning block of flats (5)
I believe the answer is:
tenet
'view' is the definition.
(a tenet is a belief or view)
'workers abandoning block of flats' is the wordplay.
'workers' becomes 'men' (men can mean staff or employees).
'abandoning' is a deletion indicator.
'block of flats' becomes 'tenement' (building containing multiple flats).
'tenement' with 'men' taken away is 'TENET'.
(Other definitions for tenet that I've seen before include "Rule" , "A belief or creed - a palindrome" , "A palindromic doctrine or creed" , "Matter of belief" , "Fundamental belief" .)
