(FORTUNE Magazine) – Stressed-out dads are coming out of the closet. According to James Levine, a director at New York's Families and Work Institute, parenting seminars offered by corporations used to be women-only forums. Now fathers like Robert Priest, creative director at Cond Nast's GQ magazine, are showing up in force and speaking out. Says Priest: "I'm having trouble managing my time -- I only have a half-hour in the morning and an hour at night to enjoy my 1-year-old son, and that's not enough." Levine says companies that pay attention to what he calls "daddy stress" will be rewarded with greater productivity. He adds: "A guy at a meeting who is worrying about getting home for his kid's soccer game is not fully concentrating on business. Let him get to the game without hassle, and he'll more than make it up to the company." A 1992 Institute survey found that nearly half of all fathers say they are stressed out trying to balance home and office. That's the same proportion as among working mothers, whose heroics in raising kids while climbing the corporate ladder earned them their own nickname in the 1980s -- the Juggler. One sign of daddy stress is a nagging sense of failure at home. Levine's prescription: Establish a regular time -- ten minutes every day, say -- to be with your spouse away from the kids. Better yet, go out together once a week too. Or take off alone for a long weekend. Many parents, though, may feel like Janet Carlson-Freed, an editor at Self magazine. "My husband and I get home at seven and want to spend as much time with our 2-year-old daughter as possible," says Carlson-Freed. "Your quality time as a couple could be taking a shower together."
