This might shock you, but lot of Austrian employers behave like this: Hire and fire. Got sick? So long. This shouldn't be acceptable in an EU country. AK is also useless here because the laws are toothless.

>unemployment benefits, social healthcare, sick leave, holidays etc

Those exist in every other EU company where you can't lay off people just because you don't like their face anymore.

>Competition against Germany, Belgium, Sweden, or the Netherlands is in my own interest.

Yet those countries score better at innovation, entrepreneurship while having better worker rights and higher wages. How do you explain that? I'm not sure working yourself to death in a race to the bottom on lowering workers rights is a good strategy.
