The Netherlands is complying with a European Directive: 2001/23/EC. In the UK, that directive is embodied in the Transfer of Undertakings (Protection of Employment) 2006 (TUPE) regulations.

Basically, the directive prevents businesses sidestepping laws and contracts that protect employees' rights by transferring those employees to another organisation. Seems reasonable to me (if you share my view that employees have rights).

They CS people in Amsterdam aren't getting fired though.

And aside from that, you can't just transfer employment contracts to random third companies in the Netherlands either.

There is nothing Marxist about The Netherlands.

Maybe if you actually read some stuff, you'd know this.
