Actually, it slipped my first reading of this and probably yours too. The wording is so 'big government' that we don't even see it: If you don't pay the financial penalties your assets are seized and you go bankrupt.
Seizure of assets is violence. You can be sure I would not like my assets to be seized because I have to follow some dumb, overreaching law. But I don't have the guns.
Holiday entitlements, probably not. However, in each country where there are things like corporations, directors can go to jail for stuff like nonpayment.
People don't go to jail for breaking workers' rights like holiday entitlements, let's not make it more dramatic than it is.
