In France where I work an offer letter is binding to hire. After that if you are fired you are entitled to strong compensation if there is no proof you failed at your job. On top of that there is significant unemployment benefits to support you during looking for a new job for years.

This seems like a normal societies way to secure the transition between jobs. I’m thankful I don’t live in any of these crazy places that make changing jobs seem like a severe stress way beyond what it should be.
