When I was a young man, at my first job, I expressed my discontent. My dad (Viggo Jensen, RIP) gave me sage advice. He nodded his head, and said "it takes about 3 years to find out what's wrong with an organization. After that it's harder." (Shockingly, this from a guy who spent 35 years in Los Angeles City Schools.)
I would not suggest that Jaclyn is wrong in her choices. Not at all. But sometimes it is a choice between working within an imperfect organization, and moving on to another .. whose flaws you will discover over the next 3 years.
