Summarize the pros and cons of working from home

The pros would be mainly the time you save, as you don't have to commute to the office, especially in cities with heavy traffic congestion and if the employee is located far from the office this is a big concern. You get some flexibility with time and you save some carbon and energy as well. 
On the other hand, the cons would be you won't get to interact physically with your colleagues, grab a coffee and connect with other peers. In the end, it all narrows down to the individual as to what works well for whom.
