TUPE stands for the Transfer of Undertakings (Protection of Employment) Regulations 2006. TUPE protects employees if their business changes hands by transferring employees and liabilities from the old employer to the new employer. It applies in cases of mergers, business sales, franchise changes, and contracting out of services. The new employer inherits all employee contracts and civil liabilities. While TUPE usually applies clearly in business transfers, some cases involving fragmented contracts require assessing factors like asset transfers and employee skills to determine applicability. Employers can negotiate warranties and indemnities, and must show an economic, technical, or organizational reason for any post-transfer dismissals or changes to terms and conditions.
