Except for the 13th month bonus, I’d say it’s pretty basic. You’d get those benefits working at a supermarket.

Five weeks vacation is a legal minimum. Most companies I worked for here in Denmark will give you six. It’s technically not five weeks, but 25 days.

I'm not European, but to a degree it seems so, yes. For example, minimum paid vacation by law is 21 days in almost all of Europe: https://en.wikipedia.org/wiki/List_of_minimum_annual_leave_b... And judging by common statements and anecdotes here on HN, I think the number of paid vacation days tend to exceed the legal minimum, especially in Western Europe, just as they do in the U.S.--typically 2 weeks for salaried employees even though Federal law mandates 0.

Likewise, mandatory pension contributions (employee and employer) in most of Western Europe exceed 20% of income (upwards of 30% in some cases), as contrasted to 12% in the U.S.: https://www.oecd-ilibrary.org/docserver/pension_glance-2017-... Who in the U.S. contributes 10-20% to their IRA or 401(k) on top of FICA payments? It's not even legal to make such large contributions pre-tax. (Some of us are privileged enough to make up the difference with higher salaries; a smaller fraction of a higher salary let's us contribute more to retirement.) Note that employer contributions aren't generally reflected in salary figures, and in some European countries employer contributions exceed 20%.

Benefits and regulations vary from country to country. I don't know details about eastern Europe, but all those are fairly common to different degrees in large parts of the continent.

Not everything standard, but quite common. Varies per country I guess. I'm thinking Netherlands.
