When I was VP of Engineering org for a startup, it was a group of about 30 Engineers at all stages of life. Some were young w/no obligations, some had families, a couple were single parents, and there were even a couple folks in the starting to have grandkids phase. I didn't particularly care what schedules people kept as long as work got done and they could be predictably reached. As a result, there were people that worked 6am to 3pm(ish), 10-3, followed by 7-10 in the evening, 11-8, etc. I had a young child and handled school dropoff, so my hours were roughly 9am - 6pm. My boss, the CEO, was a workaholic who arrived around 10am and worked to whenever. I spent an amazing amount of time dealing with "where is everyone?" sorts of questions, despite the team running fairly efficiently and still completing work on aggressive schedules.
