I recently left my main employment, for numerous reasons that I felt meant the job wasn't working out (long hours, lack of work/life balance, feeling undervalued, being promised training when there was a lack of it.) During the exit interview with my manager, my manager said the following:
I'm disappointed with your decision to leave
To this I kept quiet and said "ok" at a later stage when my former manager had finished speaking. Would there have been any more appropriate response to this statement? (which to myself seemed quite rude, as I was leaving on my own accord after a relatively short time at the company (just under a month).)
