Gerstbacher, a 50-year-old based in San Francisco, was "really unhappy" at work, he told Business Insider via email. First, he's an "older dad," and he wanted to maximize the time he could spend with his three-year-old son. "I felt that I should take the quality time now since I'll be 70 when my son graduates from high school," he said. However, the decline in working men is also due to some positive developments, like the growth of women in the workforce. AdvertisementEven though he's in the process of returning to the workforce, Gerstbacher said he's continued to prioritize spending time with his son.
