TUPE refers in practice to the automatic transfer of employees, and their existing employment rights, when a business or service is sold or outsourced. In Great Britain, it is governed by the Transfer of Undertakings (Protection of Employment) Regulations 2006 (as amended), which implement the EU Acquired Rights Directive. Northern Ireland has equivalent, but separate, Transfer of Undertakings regulations. In Ireland, the corresponding regime is contained in the European Communities (Protection of Employees on Transfer of Undertakings) Regulations 2003. TUPE applies to a “relevant transfer”, typically involving a business transfer or service provision change. Eligible employees transfer to the new employer on their existing terms, with continuity of employment preserved, and protection from dismissal connected with the transfer unless there is an economic, technical or organisational (ETO) reason. TUPE requires both transferor and transferee to inform and, in some cases, consult appropriate representatives, and to provide employee liability information. The concept and core protections are broadly consistent across the UK and Ireland, but there are differences in statutory wording, case law and service provision change rules, so practitioners must check the specific regulations and local authority decisions in each jurisdiction.
