2. Bringing yummy treats for colleagues
"This is particularly a mistake for women," said Dr. Lois Frankel, author of "Nice Girls Don't Get the Corner Office." To be taken seriously, she said, leave the baking to Betty Crocker.
"It's a nice thing to do," Frankel said. "[But] if you do it too much, you'll just be seen as the mascot, or the department mom, and you don't want that."
But at the XO Group, formerly The Knot, executives Lori Richmond and Alison Bernstein proudly call themselves office moms. They bring cupcakes to work, keep the candy jar full and maintain the office birthday calendar.
And their boss loves it.
"We are almost 70 percent women," said Carley Roney, co-founder of the XO Group. "For us to be, like, sensitive and caring and encouraging -- and motherly, if you are gonna call it that -- is part of what's made us successful."
"If you're in a culture like the Knot, by all means do it," Frankel said. "But in some cultures, that's just going to completely be a no-no." (Photo credit: Getty Images)
