Most women have no trouble re-entering the workforce after a leave of absence, a new survey finds.

Of more than 1,000 women surveyed by Make a Million $ Business, a N.Y.-based coalition of women's business groups, roughly half said they had taken extended time off in the past. Out of these, up to 88 percent said it was easy to return to work.

Still, respondents said the longer they were away, the harder it was to restart their careers. Most said six months was a good limit, the survey found.

Not surprisingly, mothers were the most likely to drop out of the workforce, though many proved more capable of balancing their personal and professional lives after returning. Thirty-five percent of moms surveyed said they managed to strike a good work-life balance, compared to just 29 percent of non-moms.
