Enforceable Undertakings (EU) are a relatively new phenomenon in the occupational health and safety (OHS) world. They are, fundamentally, a legal process that allows organisations to avoid a prosecution for breaching OHS laws. The issue has garnered some attention recently due to application of an EU to a New Zealand school after two student actors received cuts to their throats, one on the opening night of a school production of Sweeney Todd. The Enforceable Undertaking will result in big safety changes at St Kentigern School but there are several assumptions that weaken the impact of an EU.
