Get made newly redundant having pinched rear of boss (10)
I believe the answer is:
understand
'get' is the definition.
(I know that get can be written as understand)
'newly redundant having pinched rear of boss' is the wordplay.
'newly' is an anagram indicator.
'having pinched' means one lot of letters goes inside another.
'rear of' says to take the final letters.
The last letter of 'boss' is 's'.
'redundant' with letters rearranged gives 'undertand'.
'undertand' enclosing 's' is 'UNDERSTAND'.
'made' is the link.
(Other definitions for understand that I've seen before include "Make sense of" , "Grasp - sympathise" , "Get the message" , "Twig" , "Dig" .)
