I work for a large enterprise security company. I work 1 or sometimes 2 days a week from home. I spend about 6 hours in the office, usually from 10-4. My commute is really long, close to 2 hours one way, so I got my company to reimburse for a verizon jetpack, so that I can work during the commute. Apart from the window of time I spend at work, I work the remaining hours when I am in the right mindset. Sometimes, this is early in the morning, or late in the evening.
