It's exactly the same in Austria, you can always get fired without any reasons and without any severance, you just have to rely on unemployment. It still sucks though compared to other countries where you can't easily get fired, as the unemployment money might not always cover your expenses like mortgage, if you had a high paying job and got into a lot of debt for a house.

And this system of being easy to fire people hasn't exactly resulted in the well paying and plentiful jobs market the way it was promised, most likely due to the bureaucracy and high taxes on businesses, keeping investors away.

So having employees easy to fire is not the key to a good jobs market, but it's having the capital, bureaucracy and tax laws, coupled with the risk taking mentality to convince the rich to invest their wealth in starting new businesses knowing 95% of them will fail and only 5% will succeed, instead of hoarding their wealth away in multi-gernerational real estate thanks to zero inheritance taxes like the wealthy in Austria and Europe in general do.
