Resistance in the work-place (10)
I believe the answer is:
opposition
'resistance' is the definition.
(I know that opposition is a type of resistance)
'work-place' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'place' becomes 'position' (synonyms).
'op'+'position'='OPPOSITION'
'in the' is the link.
(Other definitions for opposition that I've seen before include "parliamentary group" , "obstruction" , "those out of power" , "Resistance, dissent" , "antagonism" .)
