General worker's protection (7)
I believe the answer is:
overall
This could be a double definition.
'general' is the first definition.
(similar in meaning)
'worker's protection' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for overall that I've seen before include "altogether" , "Including everything" , "Boilersuit" , "All round" , "Taking account of all the factors" .)
