They are quite conditional: you must be applying for a new job while receiving them, and after the first six months any job you can do is eligible (not just the jobs you would want to do). You must report your job applications to the unemployment agency, and you can get called in and cut off from benefits for not earnestly seeking a job.
But they are unconditional in that they are not means tested or have other clauses that could cause you to not get paid. You do not have to eat your savings, house or car. You are allowed to keep those.
Yes, the UWV [1] unemployment benefits are not perpetual (I don't recall the exact formula used to calculate the eligibility length). But even after your unemployment benefits stop, depending on the level of your savings, you may be eligible for receiving other benefits (e.g. health insurance and rent).
Overall, it is a very pro-worker system, with the major benefit of it being not "free money" (as US readers may assume), but the decreased leverage your employer has over you.

Having had to deal with parts of the Dutch system, I'm positive it's rigged against you. And you pay for it, it's literally a tax (WW premie, part of the "werknemersverzekeringen" aka employees insurance).
The Dutch system is definitely rigged in the health insurance part, where they more-or-less applied US-style privatization.
But unemployment benefits are quite ok. Yes, we pay for it, the money have to come from somewhere. But it's not that your employer would handle you the money if you didn't have WW. And it's definitely better and more stress-free than GoFundMe campaigns (either as a donor or a recipient). And, again, the tilt in the employment power dynamics in your favour is priceless.
It's in a somewhat comparable job but without regard for payment level or educational/promotional equivalence so you have to accept lower pay. The most extreme is a temp job but you have to be far gone to get there and even then there are limits.
Also, switching from a desk job to a physical job (which in this case is very physical) is not something the UWV (the goverment part which handles this) will try to bring up to a judge if you refuse as Dutch law has a "reasonability" principle and you can very easily argue that would be unreasonable.
The again, this is the UWV we are talking about. They task people with chronic fatigue syndrom to work for 20 hours a week in the fields because "their sheet says so".
The length of unemployment benefits is calculated in work years: 3 months are guaranteed, for every year worked you get 1 extra month up to 10, then 0.5 per year (changed in 2016 because the right has been in power for over 15 years).
Not that bad and you might learn some Polish or Romanian while doing those jobs as you will likely be the only Dutch person there.
