MrDenny makes a very good business logic for working from home – and I agree that sometimes the need to physically attend the office could be merely to appease those who are unable to do the same.
When I was in University, one of the instructors enjoyed joking about how we would all be working on a laptop one day, while sunning ourselves on a sandy beach, drinking frothy beverages with little umbrellas in them.
I don’t know of anyone who has ended up with quite THAT much freedom, although I do know that it is possible. The only drawback I have seen over the years is those employees who abuse any sort of priviledge or relaxation of supervision – those people who must have a supervisor hanging over their shoulder to make sure they actually do the work they are paid to do.
While my current position requires me to be on-site in each of our offices at times, I have worked from home in the past….especially while laid up for months after a surgery. It is great, it can keep people working when going into the office is not an option – and it can do all the great things that MrDenny outlined as well!
