I was once fired after sharing with my manager that I was looking elsewhere. I had other managers at the same company who were safe to share this with, but my manager at the time was not, in retrospect.

Keep it to yourself; it just isn't worth the risk.

But that’s the worst that can happen. If you’re prepared that this could be your last day, it is nice to tell them.

I told my boss later into the process when I was sure I was going to get an offer. He could have fired me on the spot, but he appreciated the extra notice.

The best thing in the world is to be fired on the day you receive a better offer. You get all of your notice pay while you are getting paid at your new employer.
