I'm a graduating PhD student looking for academic postdocs. So far, I've tried (soft-)applying to positions I found advertised online, applying for a grant and asking my PI for help. None of this has worked (yet). Especially the part with my PI has not been productive - they want me to stay for a year and apply for grants, I do not want this and it did not work for his last student who tried it.
Is it rude to explicitly ask people in my extended academic circle for help finding postdocs? My logic is that while they don't have open positions, they might know people who do. I don't want to be rude and impose on them, but I'm starting to get desperate.
