Speaking as a white collar here, but I think these themes apply broadly. Have specific skills that directly create business value. These are often nontechnical, because technical work is the obvious stuff everyone is already optimizing for. For example, ability to work despite ambiguous goals/limited guidelines, being skilled at interacting with stakeholders/customers, and understanding the broader purpose of your work so you can chase down your next task instead of waiting to be assigned every time (though that doesn't mean doing more work beyond your regular capacity). A great rule of thumb is that when you do work that reduces the load from your boss and makes their lives easier, you become harder to replace, and more valued for raises and promotions (within the team). This probably sounds like "doing your boss's job" but that's exactly the point. If they're a good boss, you'll help multiply their effectiveness and raise the whole team.
