I've never come across anybody who is so positive about the workplace as Alexander Kjerulf whose site Positive Sharing describes him as Chief Happiness Officer. Mr Kjerulf speaks and consults on happiness at work and to this end has written a book called, marvellously, Happy Hour is 9 to 5 - Learn how to Love your Job, Love Your Life and Kick Butt at Work. It's certainly a refreshing site in many ways with some interesting posts, two of particular interest to shedworkers being 12 ways to pimp your office and 10 seeeeeeeeeeeriously cool workplaces (pictured above is Kathy Sierra's shedworking trailer from this list, pictured below is her actual workspace).
As Alexander says:
"Physical space matters. It’s easier to be productive, creative and happy at work in a colourful, organic, playful environment than in a grey, linear, boring one. And I’m not talking about the outside of the building. Many companies have buildings that are sleek, modern, architectural glass-steel-and-cement sculptures on the outside - and cubicle wastelands on the inside. These companies need to remember that most employees tend to work inside the building."
Well worth a browse
