Illegal and unethical behaviour on Wall Street and in the City of London isn't just the work of a few bad apples - it's commonplace, according to new research. More than one in five financial services employees in America and the UK have seen their co-workers breaking the law or engaging in misconduct, a survey of more than 1,200 workers has found. Many feel under pressure to break the rules, believing it is a necessary part of getting ahead. Those at the top of the food chain are even more likely to have seen misconduct, with over a third of those earning more than $500,000 a year say they have witnessed or have first hand knowledge of wrongdoing in the workplace". The University of Notre Dame and law firm Labaton Sucharow, which published the report, said it showed that bankers had failed to improve behaviour, despite billions of dollars in fines, and new regulations threatening jail. "Despite the headline-making consequences of corporate misconduct, our survey reveals that attitudes toward corruption within the industry have not changed for the better," the report's authors said. The researchers ... interviewed 1,223 banking and financial services workers. The research comes the day before five banks are expecting fines worth more than $6bn related to foreign exchange manipulation. Those questioned in the survey were also asked about whistleblowing practices, and 16pc said that corporate policies barred them from reporting illegal activity to authorities.
