Well written blog post, but its a bit too adjacent to LinkedIn slop-posting in actual message, for me.

I can't help but think the real take away is that you should trust your gut and quit a lot sooner and the poster basically wasted a year being jerked around.

If you are telling your employer you are unhappy for a whole year and they don't fix the conditions leading to your unhappiness, they are telling you they don't value you enough to make those changes (for the sake of simplicity, I'll just assume the employee's specific points of dissatisfaction were reasonable fixes and not ridiculous asks).

You don't owe them a year of soft landing when you quit, in the vast majority of cases they wouldn't have given you anywhere near that if they let you go.
