I had a good job.
I had seniority because I had been there for a long time.
I could take as much vacation as I wanted.
My budget was increasing and I was supported in attending conferences and being active in my profession.
I had to leave for a lot of reasons. A friend sent me a blog post that, while describing a different field, describes my situation perfectly.
And there are spaces to find out what is next. Double Union is one of them.
