Yup, in the past decade or so these despicable companies have taken over a large part of the employment market here in Sweden, especially for younger people. Companies use it as a way to skirt employment laws by stacking multiple short-term positions on top of each other, meaning the employee is never covered by the employment protections and can be fired without compensation without reason or notice. There have been multiple instances of idiotic leaders (presumably MBAs) firing the entire staff only to rehire them through these companies with essentially zero employment protection. They charge the company about the same as they would pay for a regular employee but pay the employee much less and take the difference for themselves.

Sweden used to have really good employment protection but the past 20 years of neoliberalism (subscribed to in varying degrees by pretty much all parties except the left party, including the social democrats) has changed that, employees are now disposable cogs in a machine and nothing else.
