A company could see you are working at multiple places, but the tax authorities could say you can't work multiple full time jobs maybe? In the us I bet you could just do it. You'd have opt out of those horrible places where companies want to share your salary info. I really can't believe that is actually legal still, even though I know it is since my own salary history was mostly there. Little companies like startups I have worked in didn't do that.
