The CMI survey was undertaken at the same time the Institute published its latest Code of Conduct and incorporated responses from 1,000 employees.
Other results included 21% of those belonging to a professional body were unaware if there was a code of standards or conduct that they were required to follow. Do we have to mention that this could cause a serious problem if your employees are exposed to confidential data?
As for deliberately breaking conduct rules, it happens. Around a quarter of the UK workforce does it. And for my fellow men - we're the more likely to break the rules. The CMI say that 30% of men questioned in their survey admitted they had wilfully breached conduct guidelines.
