The work-from-home phenomenon has triggered a new problem for U.S. corporations: Americans are blowing the whistle on their employers like never before.

The U.S. Securities and Exchange Commission received 6,900 tips alleging white-collar malfeasance in the fiscal year that ended Sept. 30, a 31% jump from the previous 12-month record. The agency, which pays whistleblowers for information that leads to successful investigations, said the surge really started gaining traction in March when COVID-19 forced millions to relocate to their sofas from office cubicles.

The isolation that comes with being separated from a communal workplace has made many employees question how dedicated they are to their employers, according to lawyers for whistleblowers and academics. What’s more, people feel emboldened to speak out when managers and co-workers aren’t peering over their shoulders.

“You’re not being observed at the photocopy machine when you’re working from home,” said Jordan Thomas, a former SEC official who helped set up the agency’s whistleblower program a decade ago. “It’s never been easier to record a meeting when you can do it from your dining room table.”

Adam Waytz, a psychologist and professor at Northwestern University’s Kellogg School of Management, agreed.

“When you feel disconnected from work, you feel more comfortable speaking up,” said Waytz, who has studied the motivations of whistleblowers.

The SEC has played a big role in encouraging informants to come forward by showing how lucrative whistleblowing can be. Since the pandemic hit the U.S., the agency has paid out some $330 million in awards, including an eye-popping $114 million to a single tipster in October. While the payments are tied to SEC investigations that almost certainly predate coronavirus, the amount of money going out the door is unprecedented in the decade since the regulator started its whistleblower program.

For corporations, the rise in tips risks triggering a consequence from work from home that will last long after employees return to the office.

Even if few of the tips lead to SEC enforcement cases, companies could still be dealing with years of compliance distractions as the agency launches investigations, subpoenas documents and grills senior executives.

“Corporations and their lawyers are acutely aware of the fact that tips are flooding in and that whistleblower awards have ballooned,” said Joseph Grundfest, a former SEC commissioner who’s now a law professor at Stanford University. “You pay whistleblowers more than $100 million, you’re going to get more whistleblowers.”

The SEC gained authority to pay whistleblowers as part of the 2010 Dodd-Frank Act after lawmakers assailed the agency for missing signs of corporate wrongdoing that were later found to have laid the groundwork for the 2008 financial crisis. Another massive black eye was the regulator’s failure to catch Bernard Madoff’s Ponzi scheme despite repeated warnings from whistleblower Harry Markopolos.

Under the program, tipsters can receive financial awards if they voluntarily provide unique information that results in an enforcement action. Payouts can range from 10% to 30% of the money collected in cases where sanctions exceed $1 million. Awards are paid from a fund set up by Congress – not money owed to harmed investors.

Leveraging whistleblowers has become one of the SEC’s most potent tools for rooting out financial crime, despite the fact that most of the tips the SEC receives don’t lead to enforcement cases. Information has come from more than 100 countries, with whistleblowers providing evidence such as texts, emails and recorded calls.

The SEC never discloses the names of whistleblowers and what cases were brought with their help. Agency officials sometimes don’t even know the identity of tipsters. Thomas, the whistleblower attorney, has gone so far as to use voice-changing technology to disguise clients’ genders on conference calls with the SEC.

About $737 million has been paid to 133 individuals since the SEC issued its first payment in 2012, with most tipsters waiting months or even years after the agency wraps up its investigations to get their awards. Part of the reason payouts have quickened recently is that the SEC has streamlined its process so that enforcement lawyers who work with tipsters can actively vouch for how crucial their help was.
