I think just letting your employees know that you go to these lengths to help them if you wind up with no other choice but to let them go will be at least as valuable as "job stability" (what ever that means these days).
Every boss talks like he's going to take care of you, and (I hope) it sounds like the bullshit it is to most people. (when I hear a boss saying he's going to take care of me, I hear "I want you to do more work for me for no additional compensation") But, if when you do fire someone you do get them a better job? that person will talk, and it won't be regarded as bullshit... and you can do a lot worse than hiring people recommended or evaluated by someone that you /know/ is good.
