British companies opening a Dutch branch in case there will be a hard BREXIT. What about employees after that happens?

In one of the Dutch newspapers an article on British companies opening a Dutch branch in case there will be a hard Brexit. That way they will still have access to free trade within the EU markets. Are you wondering how to enable British employees and other non-EU personnel to work in The Netherlands during a searchyear (minimum wages), after a searchyear (3 years for a minimum of around 2500 euro a month), as a knowledgemigrant (two sets of wages requirements) feel free to contact me during the week. 

 The interesting article you can find in Dagblad van het Noorden 26th of September 2020.
