Hi guys. Please can you share tips for how to stay comfortable when working at a desk in an office for extended periods?Basically I find it almost impossible to stay sat in one place for too long at one time, let alone when you have a desk that faces the wall and you have to sit there in a suit and tie! It's so uncomfortable! The only rest I get is a 20 second walk to the toilets and maybe the odd 2 minute break at the watercooler. It's an open plan office so I can't even stand up and pace around as I make calls, nor can I really make personal calls on my mobile as a bit of a distraction. I am sure prisoners have more in the way of freedom than this.So basically I would appreciate any tips you guys may have for making life easier or more comfortable when serving 45 hours per week in the office.
