2012/2: One company cannot transfer staff to another against their will in the absence of a transfer of undertaking (CZ)
An employment transfer may only take place if there is a legal basis for it. Provision for a transfer of tasks or activities (or part of them) from one employer to another — which is a legal basis for employment transfer under the Labour Code — must be made in the contract or in another legal act, or it must consist of another legal fact. In this case, a contract between two employers stating that employees would be transferred was held not to be sufficient legal grounds for a transfer and, as such, the transfer was invalid.
