Tactless remark right to be disregarded by boss (5)
I believe the answer is:
gaffe
'tactless remark' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gaffe that I've seen before include "Social blunder" , "slip" , "Brick (that's dropped)" , "Boob" , "Tactless comment" .)
