I've gone:

Your current employer will almost always value your contributions and employment the least.

It's a sad reality that I've tried to fight with a giant stick as I've moved into management. And there are exceptions to any rule, but it's a big reason why top people leave firms. They don't feel valued. The better firms will at least do lip service to employee fulfillment and rewards but half of that is just hot air.

I was completing my three year MANAGEMENT TRAINING program with a firm when my then manager quit. It was so beautiful I could have cried. I knew I could be a good leader and had waited my whole life for this. I told everyone I wanted the job and officially applied. Heard nothing. Heard nothing. Started to make inquiries and still nothing. Months went by and no hire which was infuriating because I was right there ready to go. All kinds of things fell apart without someone in that role.

The Director didn't even have the courtesy to have a conversation with me, he sent his lackey to pull me aside and let me know that I wasn't even going to be considered and to stop asking about it. I quit a few months later and they still hadn't filled the role when I left. So lame. I really, really liked that firm too, but advancement was that important to me.
