Wells Fargo & Co. is changing how it handles whistleblower complaints after allegations that it retaliated against employees who called an ethics hotline to report sales abuses, CEO Tim Sloan said Thursday. Reuters reports that Sloan announced the change to a gathering of about 2,000 Wells Fargo employees during a visit to Des Moines. The visit was part of a “conversations tour” he and other executives are making to try to restore employee morale after the bank’s recent sales practices scandal. Sloan, who took over as CEO of San Francisco-based Wells Fargo last month, did not detail how whistleblower complaints will now be handled, but he said the bank was also reviewing allegations of retaliation against staff.
