Having good coworkers is absolutely a reason to stay in a job. You spend a lot of time at work so you want to make sure you’re enjoying that time - friends help with that.
There is no clear rule on when to leave a job, so you need to make that decision yourself (though you should talk it over with people you trust).
That said, if you’ve ever been at a company and seen one senior IC quit and then watched a conga line of other seniors following them out it’s likely that they were putting up with bullshit because they liked their coworkers and, as soon as those folks were no longer their coworkers, they didn’t see any further reason to stay. At a company with low turn over you’ll occasionally just see massive resignation waves - like 80% of a department - because the bullshit finally became too much and caused a domino effect.
