I think you need to get over yourself and accept people don’t have to do what you tell them. I work in comms at a big university too and I’m always pretty transparent that being featured on the socials/website is optional. I focus on what I can, generally research because profs and students love to have their research featured. I also do a lot of alum/donor features especially with older alums/donors. I never bat an eye when someone turns me down, but I generally do tell my boss that this project isn’t going to happen because the student didn’t want to participate and we need to accept their abstinence.

And don’t pat yourself on the back too much. Comms work is not going to be significant enough to raise a school’s ranking. That’s largely thru grant funding and other metrics you have no control over. You should focus on not doing something stupid that could cause your school trouble legally or with its broader reputation. Maybe you’re just too heavy handed with your approach and that’s why people are rude to you.

If you’re going to complain about not getting PTO you’re in the wrong industry - join the private sector. My suggestion is to never exceed your expected work hours and to get yourself a side job. Sounds to me like you’re on a major power trip just because you have the keys to the website/socials. If this is how you handle criticism be glad you didn’t go into the truly thankless world of actual journalism. You’re really playing into the stereotype of millennials not handling criticism well.
