Maintenance vs. development (Score 1)

In many cases (not all, granted) people who are in development aren't quite as plagued by work via mobile phones and beepers as are people who are in maintenance. And these are just two extremely broad categories of "knowledge workers." Also, don't forget that many of us are independent consultants and bill by the hour. Personally, I work for a consulting company (45-50 hrs/wk) and I do get paid overtime.
