I am not a fan of how he uses 'Europe' when he often means Spain and France. He clearly lacks an experience with Nordic countries (i.e. Scandinavia + Finland and Iceland), because a lot of what he says does not apply here. Working overtime is perfectly legal in Denmark for instance, if the employees prefer it (forcing them can be illegal). The reason is that in Denmark (and other Nordic countries), labour regulations…
And even then, he tends to be more wrong than right (overtime isn't illegal in France, as far as I know, although mandatory overtime is; and depending on the status of the employees overtime pay may or may not exist: broadly-speaking blue-collar workers are on the clock and paid overtime, white-collar workers are on "260 days" contrats an won't get paid extra if they work 20h/day of their own volition. They'll likely have to get paid (or get extra time off) if they have to work more than 5 days a week or during holidays)

And there usually is a delay of some sort, although in tech it can often be waived through mutual agreement.

Which, depending on the country, can be renewed once.
> firing people is more easy than usual.
Trial period is essentially equivalent to "right to work" US states: either side can terminate employment at will.
