I've never had an employer who showed any loyalty to me. I'm always valued, but when it comes right down to it, they pay attention to the bottomline. I'm fine with that; can't see the world operating any other way.
And in likewise fashion, I move on whenever it suits me. If you give me a paycheck, you purchase 2 weeks of loyalty. That's it.
I didn't build this world, I just live in it.
