I worked in State Farm for 20 years before i decided to leave (better say I was pushed out). Although it wasn't easy, this was a best decision I ever made. It's hard to say when this company turned from amazing place to work to a total nightmare, but last five years I worked there where such a emotional mess. Felt like going to prison, so much stress, micromanaging managers making people miserable and the hard work wasn't appreciated at all.
Stayed in touch with few colleagues, they say it's even worse nowadays with all the uncertainty and this reorg talk.
I had a courage to jump the ship, but I know how hard it was. So, whether you decide to leave or wait to see what happens, I wish you all good luck.
Just know that there is a life after SF after all.
