As a European (for now, oho) this doesn't surprise me at all. American working patterns are bonkers. You guys have this concept of 'vacation' which well, isn't. 15 days or whatever per year pretty much all just must either get banked for emergencies, admin, or maybe that one Mega Holiday where you fly across the world and spend a week or whatever trying to forget your life. I don't get it at all. It might make sense…
I'm genuinely curious; how many days do Europeans typically get?
"Almost all workers are legally entitled to 5.6 weeks’ paid holiday a year (known as statutory leave entitlement or annual leave)."
So 28 days.
Personally I've usually had about 25 days + bank holidays in contracts as standard (i.e. before negotiation), so 33 days in total.
The main distinction though is that because we don't have this 'health insurance tied to work' thing going on, it's at least theoretically possible for a median wage earner who hasn't loaded themselves up with debt to take a decent amount of time off by just leaving their job. Whether they actually do it doesn't matter - there's at least the mental release valve of knowing you can quit.
In the US it sounds like you could get away with that as a healthy 20 year old otherwise you'd be playing the lottery.
