Now CNNMoney is hearing from former Wells Fargo (WFC) workers around the country who tried to put a stop to these illegal tactics. Almost half a dozen workers who spoke with us say they paid dearly for trying to do the right thing: they were fired.
"They ruined my life," Bill Bado, a former Wells Fargo banker in Pennsylvania, told CNNMoney.
Bado not only refused orders to open phony bank and credit accounts. The New Jersey man called an ethics hotline and sent an email to human resources in September 2013, flagging unethical sales activities he was being instructed to do.
Eight days after that email, a copy of which CNNMoney obtained, Bado was terminated. The stated reason? Tardiness.
One former Wells Fargo human resources official even said the bank had a method in place to retaliate against tipsters. He said that Wells Fargo would find ways to fire employees "in retaliation for shining light" on sales issues. It could be as simple as monitoring the employee to find a fault, like showing up a few minutes late on several occasions.
"I endured harsh bullying ... defamation of character, and eventually being pinned for something I didn't do," said Heather Brock, who was fired earlier this month as a senior business banker at a Wells Fargo branch in Round Rock, Texas.
