That's awful and terribly relatable. Sorry you had to go through that. Job market is terrible. Had one interview after 15 or so applications, but there's not much else. Strongly considering trying to get a Canadian work visa and expand my search.
One of the reasons my manager wants to replace me is that he asked me to give someone access to edit our website. I said I don't manage the website and don't have access myself. I have no training or background on the website. I have a contact number if there's a network issue but that's it. Apparently when I agreed to be the network manager, that also included webmaster, but one without credentials, support, or personnel. Basically he wanted me to do all the things my old boss did, while continuing my old job, and with a downsized department. The more I think about it, the angrier I am about how much I have been set up to fail, and I don't understand why.
