If you hire someone for 100k per year and it turns out they only contribute 50k per year, then you lose a minimum of 25k over those six months.

As a business you're more risk-averse in offering high salaries since it costs more when you make a mistake.

You can actually fire people with only two weeks notice during the first 6 months. I think the risk really is that nay inherent flaws in a highly paid employee are not detected early, and to fire them later is indeed very costly and complicated.

2 weeks notice in the first 3 months, 4 weeks in the second 3 months. This works both ways, both sides are free to terminate without stating the reason.
