Eastern workers in their part of the world right to use what is not theirs (8)
I believe the answer is:
easement
'the world right to use what is not theirs' is the definition.
I can't tell whether this defines the answer.
'eastern workers in their' is the wordplay.
'eastern' becomes 'e'.
'workers' becomes 'men' (men can mean staff or employees).
'in' indicates putting letters inside.
'their' becomes 'east' (I am not sure about this - if you are sure you should believe this answer much more).
'e'+'men'='emen'
'emen' inserted inside 'east' is 'EASEMENT'.
'part of' is the link.
Can you help me to learn more?
(Other definitions for easement that I've seen before include "The legal right to cross or use another's land" , "Right to cross another's property; peace" , "giving right of access to adjacent area?" , "right of passage" , "landowner's right" .)
