>30 paid holidaysI'm always angered by these over-generalizations for the whole of Europe. Europe is not a single country with identical laws and working conditions but they differ wildly by borders.
The minimum amount of vacation days by EU law is 20 per year for every full-time worker in the EU but workers can get more based on union negotiations of each individual country or individual company perks that wish to attract talent.
In Austria, the norm is 25 paid vacation days a year for all full-time workers including tech workers. I rarely saw more that 25 days of vacation offered for tech workers here even at supposedly "top" companies which Austria doesn't have many of.
>paid overtime
Same for this. In Austria, most tech jobs don't pay overtime (thanks to shitty "all-in" contracts) but, factory style jobs with clocked shift-work do, since those are usually unionized and the metall workers union is one of the strongest in the country. Also many jobs, especially in public healthcare sector do a lot of unpaid overtime due to underfunding and staff shortages. In low-skilled jobs with high competition, like hospitality and cleaning services, unpaid overtime and your boss being abusive is pretty much the norm.
>Ah, and in some countries having too many companies on the CV isn't well seen
Gee, let me guess, hyper-conservative, 100-year-old German boomer companies(factories)? They're free to expect that, but staying 10+ years at the same company was good way-back-when there wasn't rampant inflation, and rampant real-estate prices, and a factory worker could support a family and buy a home from his income and he'd be employed till retirement and the company would always invest in his training. Those days are long-gone now thanks to globalization, offshoring of jobs and unrestricted immigration, so any company is happy to keep your wage growth below asset inflation levels as you loose out and the company wins as inflation is eating their loan paybacks and the salary they have to pay you, so the only way for you to claw back some of those losses is to job-hop (if you can).
And if you don't like it, there's nothing you can do about it if you don't have skills in high demand in a filed suffering from a shortage in your domain, as unlike the 1960's when even workers with basic education(high-school) had leverage, the company can now hire through a plethora of more candidates thanks to easy immigration, or offshore your job completely to a palace with less employee/environmental protection, while paying fuck-all in taxes through their shell company registered at a post-box in Luxembourg, basically depriving workers of most of their leverage they had in the past. That's why political parties on both extremes of the spectrum are seeing a resurgence in Europe. If we don't fix the rampant wealth inequality yesterday, we're gonna see political extremes and civil unrest growing stronger in Europe. Which is why I guess the EU nation states are so keen on gaining more surveillance powers and banning encryption, to make sure they stomp out any civil unrest before it happens.
The biggest perk we have in most EU countries is paid sick leave and health insurance if you lose your job. If your health ever declines and you end up loosing your job this is invaluable to not becoming homeless. Although many of those social benefits suffered cutbacks and receiving them became stricter in some countries after the 2008 recession.
