If it were me I’d set up a makeshift work station in obnoxious locations. Make it really obvious I wasn’t given a proper place to work and make it seen by all the higher ups and visitors. Do it every day. Change locations so it’s always new spots. Always in locations where people bottle neck so they can’t avoid you.

If I have to take it to the next level then I start working on the floor. Get my charging cable out so it stretches across the floor. Set out a bunch of papers all across the floor to make it look like I’m working on something big. Make people have to walk around your papers to avoid interrupting your work.

No doubt people start taking and asking questions. Then you start throwing around how much work you have to do but have no proper place to do it so you’re doing everything in your power to get by and get the job done. Then be sure to loudly excuse yourself from the conversation and make sure they know you have a big dead line and don’t have time for chit chat.
