By way of explanation I'm a computer service tech who handles on-site support for network connectivity, computer hardware/printers, software support for supported applications, etc.. I was the last tech on-campus the week that we locked down due to Covid. My group is the only one that consistently has representation on campus, within the overall IT group. I'm on-site 2 days a week and work from home 3 days a week. I've been on this job for almost 25 years now and in that time we've had things like phones dumped on us (went from digital to IP phones and were told, "Well, they're just little computers anyway."), cellular phones (which no one was supposed to provide support for), and the like.
EDIT - Oh, yeah. I completely forgot the time that they eliminated the entire group of techs that took care of the student labs, with a couple of thousand computers, and dumped that on us.
Because of lockdown and the subsequent move to a hybrid work model it seems that other groups have decided that we have to be their legs and arms, on campus, rather than hauling their own butts out of their comfortable, company paid-for home office chairs. The group that deals with debit/credit card readers expects us to troubleshoot issues for them, by claiming "it's a network issue." Networking wants us to troubleshoot down connections because "it's a hardware issue." People even call us to turn on their on-site remotely accessed computers, when they do something like hit shutdown instead of log out, because they're too lazy to do it themselves. Hell, the departmental receptionist doesn't even come on-site so we're dealing with mail. There are 6 of us, to cover a whole campus, and 3 are on-site at any given time. The hybrid work model is definitely working well. For everyone else.
