The U.S. Commodity Futures Trading Commission on Monday took steps to strengthen its rules regarding whistleblowers in order to protect tipsters from retaliation or being silenced by their employers, Reuters reports.

Under the new rules the CFTC says companies cannot try and stop a would-be whistleblower from speaking with the agency about possible violations of the federal derivatives laws.

"The whistleblower program is an integral part of the division's efforts to identify and prosecute unlawful conduct," CFTC Enforcement Director James McDonald said, according to Reuters.
