Well I definitely don't refer friends here. But I also do recruit people. I do take care of the people I recruit by shielding most communication between the new hires and the CEO. I also believe that I need to plan an exit strategy by recruiting people that could replace me because the others cannot.

If you're just an employee, it's management's responsibility, not yours, to make sure the company can survive your leaving.

You shouldn't feel guilty about quitting, since they'd fire you in a minute without any warning if it was convenient for them.
