Plan B is to do short-term contract work as a result of connections from current and past PDFs. I promised my graduate supervisor that I would keep trying for a tenure-track position for 4 years so I have a few more years of these types of applications ahead of me.
Once those 4 years are up (and I expect I won't have a tenure-track position at that point, because....current market), I will be looking into industry-type jobs. I want some stability as I am hitting my mid-30s, would like my mental health to not decline this rapidly, etc etc.
