Path to take on getting dismissed... (5)
I believe the answer is:
route
'path' is the definition.
(synonyms)
'on getting dismissed' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'getting' means one lot of letters goes inside another.
'dismissed' becomes 'out' (I've seen this before).
're' going around 'out' is 'ROUTE'.
'to take' is the link.
(Other definitions for route that I've seen before include "' - - 66', Nat Cole song" , "Path taken" , "Way to travel" , "Established line of trave" , "Way, line" .)
