Not necessarily. I work in a relatively small town with 2 companies in it, both companies employee >10,000 people each. You'd think that there would be horrible traffic but there isn't. One company starts the day at somewhere between 6 and 8, while the other company starts the day between 8 and 10. It is just a coincidence I think, but it really works out for traffic. I know most people are horrified at the thought of showing up at work at 6am, I went from a job where I started the day at 10am to this one and was shocked. I typically get in around 7am even though my boss is in earlier. But we're leaving at 3 or 4pm, and I get to go surfing after work (helps to be 5 minutes from the ocean). It has its advantages.
