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 to make it look like I’m working on something big.
