I second the privacy screen; the person who handles contracts where I work uses one, and it’s very effective. (If you don’t handle documents at a high enough level to really need such a screen, maybe try saying that you need it to block blue light?).
I haven’t tried accessing the board at work in years, mainly because of the number of posts I’ve made about my workplace. I probably couldn’t access it now anyway, given some of the stuff that gets blocked.
