It's not just about quitting Microsoft to Join google, It's also about quitting Mcdonald's to join Subway, or quitting Amazon to work for Walmart. The only workers who aren't able to quit a job are public sector workers, where the government has a monopsony on hiring.
> I've yet to work anywhere with mandatory vacation days in the sense that I can not give them up In some countries you can give up your paid vacation days. At a cost to your employer who would have to PAY YOU additionally. These all add up as additional costs of employment, and simply reduce the salary you earn in the first place. (As compared to what you could earn if there weren't paid leave laws in place).
Do some workers and employers prefer a lower salary for more vacation days? sure. Just agree on that as part of a contract. Don't force a one size fits all solution on everyone.
> Women leave employment in droves to have children whether or not they get paid maternity leave I wasn't addressing that. I was explaining that in countries that have paid maternity leave, women might not even get employed (or only get employed for certain roles) in the first place.
> Mandatory insurances and pensions are not about workers protections per se most places I'm aware of. Take Israel as an example. Mandatory pensions are considered a "triumph" of the unions, who are able to strongarm employers in to paying more into worker's pensions: http://www.globes.co.il/en/article-histadrut-employers-agree...
> Not being able to fire a worker is not a common feature of workers protections anywhere. It's never about "not being able to fire". It's about firing flexibility. Can an employer simply send you home, or do they have to go through lots of legal beuracracy first?
It's easy in Denmark: http://www.nytimes.com/2004/12/15/business/worldbusiness/the... But difficult in France or Germany: https://www.quora.com/Is-it-true-that-its-impossible-to-fire... https://www.wbs-law.de/eng/doing-business-germany/employment...
The bottom line is that if it's difficult to fire someone, you'll be a lot more picky and careful before hiring them.
