It's a familiar stereotype. The part-time worker (usually a woman) who has compromised on career and salary to bring up children.
Not for her the world of her full-time counterpart (usually a man) in a high-powered job, with not enough hours in the day, let alone days in the week, to respond to the e-mails, phone calls and meeting requests coming at him from all corners of the globe.
But a decade and a half into the 21st Century there are signs of a work pattern emerging that fits neither stereotype. And it isn't only for the benefit of frustrated working mothers.
It's being forged by men and women who, for whatever reason - whether it's children, elderly parents, or the pursuit of that elusive thing called work-life balance, don't want to work full-time, but are determined to do more than just "keep their hand in".
"I still feel ambitious. I want to have influence. There's an assumption that when you ask for part-time work, all those other things that made you professionally have gone out of the window, and that's just not true," says Karen Mattison, the co-founder of Timewise, which promotes flexible working.
"You're the same person inside, that's why the stigma around part-time work matters, it's the lens you might be looked at through."
