There are many different types of employee misconduct from insubordination to abuse of sick leave. Some employee misconduct is obvious. Insubordination is easy to uncover, because it doesn’t involve deceit, it involves an employee intentionally disobeying a superior.

Earlier this year, Britain’s Home Office UK Border Agency fired an immigration officer who used his security access to add his wife’s name to Britian’s ‘no fly’ database. The most interesting part of this story was the fact the immigration officer put his wife’s name on the list more than three years ago, after the wife flew to Pakistan to visit family, thus preventing her from being able to return to Britain. The immigration officer’s actions were finally discovered when he applied for a promotion and an updated background check was required. It revealed he was married to someone on a terrorist watch list. When confronted, he admitted he tampered with the list.

When you discover misconduct, even if it happened in the past, it is still important to act and investigate the misconduct.
