Neither will see a raise or promotion. That's an easy one. Rule number one is not to trust your employer. Be on the constant lookout for better pay. That's what good workers do.
If everyone thought like you, which to be fair a lot of workers do....is the reason we have a lot of shitty workers.
I tell all my employees, do your best, at work, in life, there's no difference. If you're not being the best you that you can be, every minute of every day, you're shortchanging yourself. The people that do, end up getting promoted because of their work ethic when opportunity arises.
The ones who don't, quit or get fired almost always with nothing to go to. Why? Because I didn't fisking give them anything. Want it? Earn it.
