6 executives who make a point of leaving the office before dark

Jabal previously shared her daily work schedule with Business Insider: "Home an hour in the morning, get kids to school, work in the office 9 a.m. to 5 p.m., have dinner with kids, work three hours at night."

Jabal acknowledged that it can be hard to maintain these hours if your organization doesn't offer some flexibility. "Rigid work hours and work location make it much more challenging," she said.

Lockheimer told Business Insider's Aine Cain that he drops off his two kids at school every morning before going to work. "That's almost religious for me. That's something I really enjoy doing and I insist on doing," he said. He generally gets to the office around 9 a.m.

Lockheimer typically leaves the office at 5:30 p.m. so he can eat dinner with his family. Like Sandberg, once the kids are in bed, he'll grab his laptop to catch up on work.

In a 2017 interview with Glassdoor, Rascoff said that at 7 p.m., "I am almost always with the kids and my wife unless I’m on a business trip. At 7 p.m., I am usually running around my house chasing my three young kids and two dogs and trying to turn mayhem into order."

Rascoff also wrote an article for Fortune in which he explained why he doesn't expect Zillow employees to be working 24/7, like he did in the early days of Hotwire, the company he cofounded in 1999. Instead, Rascoff wrote that Zillow understands "each of us is a whole person and lives for more than just our jobs."

Years before joining VMware, Gelsinger worked at Intel, where he'd regularly log 80-hour workweeks.

But for the past 25 ears, Gelsinger told The Wall Street Journal, his secretary has kept a chart tracking the points he earns based on how much time he spends with his family.

Here's an example of how it works: If he arrives home by 6:30 p.m., he earns a point. If he arrives home by 5 p.m., he earns two points. If he's away from home on the weekend, he has points deducted.

Gelsinger, who is the author of the 2003 book "The Juggling Act: Bringing Balance to Your Faith, Family, and Work," said the rules have changed somewhat since his kids left home.

"If you have kids, 6 to 9 p.m. is gold. Do not squander it. You might get back on email at 9 p.m., or be doing Javascript at midnight, but make sure you carve those hours out [for family time] and protect those," Gelsinger told Business Insider's Julie Bort.

"I walk out of this office every day at 5:30 so I'm home for dinner with my kids at 6," Sandberg said in a 2012 Makers interview.

According to Fortune, Sandberg sometimes gets to the office by 7 a.m. — and she's already been sending emails for an hour. And after the kids are in bed or the night, she'll generally head back to her inbox.

In the 2012 interview, Sandberg said it took her a while to feel "brave enough" to talk about his practice publicly.
