Of course it is. And what's wrong with that?
Mr. Freeze Peach doesn't seem to complain about that when it is China calling the shots. If he wants to play in Sweden, he can play by local rules.
There is nothing illegal about operating without a collective labour agreement in Sweden. For example, I’m born in Sweden and have worked here for 20+ years and I don’t think I’ve ever had an employer with a collective labor agreement. Among tech startups and smaller companies it’s quite rare, and when I’ve worked for larger companies I’ve incorporated and contracted, largely to get away from the negative effects of unions and job security: absurdly low pay.
