I check (and sometimes respond to) business email during off hours, out of curiosity. Also, some of our customers and partners are in very different time zones, and it speeds things up to answer a question or open a ticket to solve a problem immediately rather than waiting 12 hours. My manager and I are both a little fanatical that way. It's not a requirement of the job but it does distinguish our lean, efficient little intrapreneurial unit from the stodgy, slow responsiveness of the rest of the company.
