At work see about upper limit, finding way out (6)
I believe the answer is:
escape
'way out' is the definition.
(thesaurus)
'at work see about upper limit' is the wordplay.
'at work' is an anagram indicator.
'about' indicates putting letters inside.
'upper limit' becomes 'cap' (I've seen this before).
'see' with letters rearranged gives 'ese'.
'ese' enclosing 'cap' is 'ESCAPE'.
'finding' acts as a link.
(Other definitions for escape that I've seen before include "Get away from the strange EC peas" , "it was great for Steve McQueen!" , "Evade" , "Elude; break free" , "Make a run for it" .)
