Serious misconduct is often spoken about as though it were fixed and well understood. In practice, it is anything but static. While conduct such as theft, fraud and sexual harassment remain clear examples, case law shows an expanding and more nuanced approach to what may justify summary dismissal.

Serious misconduct is not defined in the Fair Work Act 2009 (Cth), but the Fair Work Regulations 2009 (Cth) (regulation 1.07) provides guidance with examples such as theft, fraud, violence and serious breaches of work health and safety obligations.
