(Reuters) - Wells Fargo ( WFC ) last month terminated over a dozen employees after reviewing allegations that they were involved in simulation of keyboard activity, creating an impression of active work, Bloomberg News reported on Thursday.

The fired employees worked in the bank's wealth and investment management unit, according to the report, which cited the bank's disclosures filed with the Financial Industry Regulatory Authority.

"Wells Fargo ( WFC ) holds employees to the highest standards and does not tolerate unethical behavior," a spokesperson told Reuters.

It wasn't clear from the regulatory disclosures if the employees were fired for allegedly faking active work from home, the report added.

Wells Fargo ( WFC ) in early 2022 had asked most of its employees, including those in customer-facing roles, to return to office and work under a hybrid flexible model.
