Working from home is often seen as the Holy Grail of the IT worker. No more getting up early to get ready for work. No more spending thousands of pounds a year for a season pass only to get squished in a carriage like a sardine.My last office commute was three hours each way. If the option of working from home had been available to me, I would have grabbed it with both hands. This is a particularly popular option that my current employer uses when they want to hold on to good employees who move, or otherwise can no longer attend the office.
