Salaries and wages have always been a hot-button issue no matter what industry you may work in.

For the second year in a row, a majority of U.S. publicly traded companies such as Amazon, JPMorgan and Walmart have disclosed how much their employees earn on average and, more importantly, how that pay compares with its CEO’s salary.

The employee-pay disclosure was first mandated by the 2010 Dodd-Frank Act after the 2008 financial crisis to help shareholders get intel on executive-compensation practices at major U.S. firms. However, last March was the first time U.S. publicly traded firms were required under federal regulations to divulge the information along with its CEO’s pay and the ratio between the two.

The Journal then took that data from MyLogIQ and created a chart across key industry sectors such as energy, tech, finance, health care, industrials and consumers to help workers find out where they stand.
