A friend of mine used to work for a bank which changed premises, and introduced hot-desking. They only had 80% seats and planned for all staff to work at least one day from home. "I'm a netadmin. I can't work from home to do my job properly" eventually swayed them into giving him a permanent desk.

But hot-desking was still a complete failure, even excluding the personalisation issues. He said that people would arrive at the floor asking 'Is Bob here today?', to which could only be answered 'I don't know, he could be anywhere on the floor. I'd have no idea of where to look for him'.

Some people like open-plan, and some people hate it. But I've never met anyone who liked hot-desking.
