I found out today that my current compensation is low for my exp/prof/skills. I asked about getting better compensation rather than immediately leaving and was asked to submit the request with supporting documents showing that my peers have a significantly higher pay/rewards than I do. Does anyone know of any good sources to make this a bit easier? I've got a decade of IT experience and have spent the last 4 years as a devops engineer/solutions architect. I'm likely gone this year, but it would be handy going forward to know how to assess my own professional value.
