I'm far from perfect as a manager, but I've always worked to help employees working for me evaluate their career options inside and outside our company. I've had open conversations with my bosses about what my goals, skills, limits, etc. were. Many times, I've "saved" employees (from quitting) by helping them see a better path here than they expected was possible. Other times, I've said "holy crap, that sounds amazing and, even though I really value having you work here, I have to advise you that I'd make the jump if I was in your shoes." I've told my boss when (and why) I was interviewing for other roles. I've also told them when I've been totally satisfied and not intending to look for a while.
I could work for a boss that I couldn't trust with that data, but I much prefer working for one that I can and I try to be the one that my directs can trust with it.
