So when a company wins a contract they have to offer jobs to those who already do the work then, under EU laws
Transfer of Undertakings (Protection of Employment) Regulations 2006Quote:
The Transfer of Undertakings (Protection of Employment) Regulations 2006 (SI 2006/246) known colloquially as TUPE, are the United Kingdom's implementation of the European Union Business Transfers Directive. It is an important part of UK labour law, protecting employees whose business is being transferred to another business. The 2006 regulations replace the old 1981 regulations (SI 1981/1794) which implemented the original Directive.
