And when I worked in high end rnd if we brought kit on behalf of a client to use on their projects we charged them AND A 25% MANAGMENT FEE.
The company is not your friend as people often say on here but buying equipment for them is OK FFS
Here's an idea: instead of expecting the employer to provide more than a basic level of ergonomics and potentially having to go through all the bureaucratic and mental hoops, both on receiving and on returning, we just.. pay the employees more money so they can decide for themselves.
Why you're putting this in the frame of "employer is not your friend" is beyond me, no one was framing it that way to begin with. If anything, it is because we can't expect employers to deliver beyond a basic level and introducing all these rules to make it harder, that it makes more sense to bite the bullet up front and be in control.
