Ha, at my partner's work(large IT company in UK) they are not even allowed to move or adjust the height of their own desks, because it's a health and safety violation and if anything happened to them doing it the insurance wouldn't cover them. I think HR would get a heart attack at the thought of employees assembling their own desks.
Yea i always found this funny. I was not allowed to move a monitor in the office, but was racking 4u servers by myself in the datacenter. When i asked they claimed it was because the insurance for the monitor, not me, would not be covered if it was not the local IT guy who moved it.
