As a manager of engineers I would definitely recommend showing up and trying to kick ass every day no matter what. If you're feeling like you're under paid feel free to discuss it with your manager and get another job if you feel that is the right move for yourself. Please don't show up and sulk at work and make life miserable with a work stoppage though.
Most times your immediate managers have very limited control of salary decisions and certainly your team mates and customers have almost none. While you may have a professional disagreement with your company about compensation please don't let that ruin your personal reputation and relationships by doing sub par work, continue to build that reputation and relationships with excellent work.
As a personal example I had a compensation disagreement with a company I worked for. After not getting the raise I requested from my manager I still delivered a superior product that is the basis of that companies business to this day. Up until I left for a better paying job 6 months later I did everything I could to deliver the best for my team mates and customers. Two years later my former manager became VP at a new start up and hired me on with a solid salary and equity because we still had a strong personal and professional relationship even if the company we had previously worked for had problems.
