We already know CEOs of major corporations took home 354 times more pay than the average rank-and-file U.S. worker in 2012. Now, we have the opportunity to see what CEOs make compared with the typical worker in their own companies.

A rule proposed by the U.S. Securities and Exchange Commission (SEC) would require companies to disclose the ratio of total compensation between CEOs and the pay of the typical worker. The SEC rule is part of the Dodd–Frank Wall Street Reform and Consumer Protection Act of 2010. Major corporations like Walmart really don't like this, which is why we need your help.

If you want more transparency when it comes to what CEOs are paid compared with the people that make those companies run, please send a letter to the SEC supporting this rule. The comment period ends Dec. 2.

Tell the SEC companies must disclose CEO-to-worker pay ratios.

If you are an investor, make sure you identify yourself as one in the letter.
