Arguably, it would've been a much better system if the Netherlands just... paid people directly regardless of who they worked for at the time, so employers didn't need to worry about paying employees while they couldn't do normal business.
Instead they should have let businesses lay off staff without feeling guilty because there was a safety net for those people and once a business laid off X% of their staff they could have been eligible for extra government help.
That way the government wouldn't have ended up paying the wages of people that were needed to meet demand (and make profit for) the businesses that weren't really impacted.
For example, local restaurants got crushed and could easily justify laying off 50%+ of their staff. Give them more money IMO. However, the delivery business down the street with +50% demand shouldn't be getting a nickel.
Nevertheless the systems do exist. Financial aid was and even still is there for you or your business if you need it.
