Here's your reminder that 20-30 days paid vacation plus unlimited sick days (3+ days needs a doctor's note) is normal in Europe (e.g. Germany).
If you get sick during vacation, you get those vacation days "refunded" back. If you suddenly are called in to work, somehow, during vacation, that time cannot be vacation time.
You can't (generally) be fired without a notice period, resulting in job security to such a degree that ~6k in an emergency fund is plenty to be VERY secure, as you also get unemployment support otherwise anyway. Does this result in incompetent people not getting fired? No. You still fire them, you just have to deal with them another month after that. It's not a big price to pay.
How is this all possible? Who subsidizes it? We all simply pay some % of our income to support this system. That's it. A couple percent, a couple bucks, and we get to basically never worry about starving or becoming homeless.
You can have this, too, if you vote and protest and use democracy to make life better, not worse, for everyone.
