I have just started a new job. I am in a 'rabbit warren' of 4 people with my desk and positioning of my computer which makes my back to the door plus a couple of other people. I cannot change the desk as its all incorporated with the others, or move my computer to make much difference. I don't wish to get obvious, but what can I do which will help the 'back to the door - or opening' problem that I have. Thanks
