To add to the other side. I cannot imagine not having a capability to just gather my things and leave. All it takes is savings that can keep you running in modesty for 6 months. In my country, including health insurance, without mortgage/debt/kids its about 10k usd ("central" europe).

Its not much honestly. Peace of mind and poker plays you can swing towards shity employer are worth it. 6 months to find new SWE job, when I constantly pinged by HR and have generally good relations with previous employers(they would take me if i ping them), is plenty of time
