I can't help but think that this post is astroturfing by a company that keeps losing its employees due to better conditions elsewhere. The thought of feeling guilty for an employer is preposterous to me.
Not necessarily employer, but you can easily feel guilty for a team. I did when i left a few months ago because i knew i was a valuable contributor, there was lots of stuff going on and that it'd take a long time for me to be replaced, leaving the people I've worked with for years, and whom i liked, under extra pressure.
I really liked the mission of the company I worked for. The management was poor and they did nothing as they saw my coworkers going out the door. Then I left too. That doesn't mean I want to see my former company and its mission suffer. That may not be completely rational but preposterous seems a bit harsh.
